I’m trying to figure out this issue for 6 hours. But there is nothing to make sense. Here is the scenario; There is a well formatted HTML template.

$mail_body = '
    <b>Message Num :</b> 769<br />
    <b>Message Date :</b> 2013-04-08 09:03:21<br />
    <b>Name :</b> John Doe<br />
    <b>Phone :</b> 123456789<br />
    <b>E-mail :</b> abcdf@somedomain.com<br />
    <b>Message :</b> Here is the message info<br />
';

Here is the array of recipients’ mails;

$recipients = array("abc@something.com","xyz@somtehing.com");

Everything looks fine and email ready to send.Here is the phpmailer config;

$mail = new PHPMailer(); 
$mail->IsSMTP();
$mail->From = "noreply@something.com"; 
$mail->FromName = "TEST";
$mail->WordWrap = 50;

foreach($recipients as $mail_add) {
    $mail->AddAddress($mail_add);
}
$mail->IsHTML(true);
$mail->Subject = "TEST Subject";
$mail->Body = $mail_body;
if(!$mail->Send()) {
    echo $mail->ErrorInfo;
} else { 
        echo "Mail sent...";
}

Everything is same when I test it. But sometimes email was sent. Sometimes it was not sent. Give me the following error : The following SMTP Error: Data not accepted.

I hope I explained

For AWS users who work with Amazon SES in conjunction with PHPMailer, this error also appears when your «from» mail sender isn’t a verified sender.

To add a verified sender:

  1. Log in to your Amazon AWS console: https://console.aws.amazon.com

  2. Select «Amazon SES» from your list of available AWS applications

  3. Select, under «Verified Senders», the «Email Addresses» —> «Verify a new email address»

  4. Navigate to that new sender’s email, click the confirmation e-mail’s link.

And you’re all set.

Interestingly, I had the same exact issue and for me the problem was that my connection was timing out. To be able to see more details on my connections, I added $mail->SMTPDebug = 4; to my phpmailer (look up how to capture the debug since the default output function is echo).

Here’s the result:

SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is ""
SMTP -> get_lines(): $data is ""
SMTP -> get_lines(): timed-out (10 seconds)
SMTP -> FROM SERVER:
SMTP -> ERROR: DATA not accepted from server:

The default timeout is set to 10 seconds. If your app can support more, add this line to your phpmailer:

$mail->Timeout = 20;

Over a certain message of size, it messes up the content when setting through $mail->Body.

You can test it, if it works well with small messages, but doesn’t work with larger (over 4-6 kB), then this is the problem.

It seems to be the problem of $mail->Body, so you can get around this by setting the HTML body manually via $mail->MsgHTML($message). And then you can try to only add the non-html body by $mail->AltBody.

Hope that I could help, feel free to provide more details, information.

I was using just

$mail->Body    = $message;

and for some sumbited forms the PHP was returning the error:

SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: This message was classified as SPAM and may not be delivered
SMTP code: 550

I got it fixed adding this code after $mail->Body=$message :

$mail->MsgHTML = $message;
$mail->AltBody = $message;

We send email via the Gmail SMTP servers, and we get this exact error from PHPMailer sometimes when we hit our Gmail send limits.

You can check if it’s the same thing happening to you by going into Gmail and trying to manually send an email. In our case that displays the more helpful error message about sending limits.

I was hitting this error with phpMailer + Amazon SES. The phpMailer error is not very descriptive:

2: message: SERVER -> CLIENT: 554 Transaction failed: Expected ';', got ""
1: message: 
2: message: SMTP Error: data not accepted.

For me the issue was simply that I had the following as content type:

$phpmailer->ContentType = 'text/html; charset=utf-8rn';

But that it shouldn’t have the linebreak in it:

$phpmailer->ContentType = 'text/html; charset=utf-8';

… I suspect this was legacy code from our older version. So basically, triple check every $phpmailer setting you’re adding — the smallest detail counts.

First you better set debug to TRUE:

$email->SMTPDebug = true;

Or temporary change value of public $SMTPDebug = false; in PHPMailer class.

And then you can see the full log in the browser.
For me it was too many emails per second:

...
SMTP -> FROM SERVER:XXX.XX.XX.X Ok
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> get_lines(): $data is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> FROM SERVER:XXX.XX.XX.X Requested action not taken: too many emails per second
SMTP -> ERROR: DATA command not accepted from server: 550 5.7.0 Requested action not taken: too many emails per second
...

Thus I got to know what was the exact issue.

I was experiencing this same problem. In my instance the send mail was timing out because my Exchange server was relaying email to a server on the internet. That server had exceeded it’s bandwidth quota. Apparently php mailer has some built in timeout and it wasn’t long enough to see the actual message.

If you are using the Office 365 SMTP gateway then «SMTP Error: data not accepted.» is the response you will get if the mailbox is full (even if you are just sending from it).

Try deleting some messages out of the mailbox.

It happen too, when you used stripslashes or addslashesh or real_escape_string.

Avoid these things inside email body, when your email execution code completed then you can add these lines in bottom.

Статья была полезной?

Если сообщение не было доставлено получателю, то ему будет присвоен один из следующих статусов:

  • Отменено/Запрещено — если отправка сообщения ограничена со стороны внутреннего функционала GetCourse. Например, пользователь забанен, отписался от категории или перестал удовлетворять условию рассылки.
  • Ошибка — если сообщение было отклонено почтовым сервером. В таком случае в аккаунт поступит отчет с текстовым описанием ошибки. Проанализировав ошибку, можно понять причину, по которой сообщение не было доставлено.

В статье разберем основные виды ошибок при отправке email-рассылок и рекомендации по работе с ними.

<h4>Пример возвращенной ошибки. В деталях ошибки видим, что почтовый ящик пользователя был переполнен.</h4>

Пример возвращенной ошибки. В деталях ошибки видим, что почтовый ящик пользователя был переполнен.

Ссылка на это место страницы:
#main

Текстовое описание одной и той же ошибки может отличаться в зависимости от почтового сервиса, который ее возвращает. Например ошибки:

  • Mailbox does not exist. We do not relay
  • No such user!

Означают, что эл. адрес пользователя не существует.

В статье мы перечислили известные описания ошибок и условно поделили их на несколько категорий:

  • Ошибки в названии электронных ящиков
  • Ошибки в названии домена или его настройках
  • Почтовый ящик пользователя переполнен или заблокирован
  • Попадание в спам на почтовом сервисе
  • Грейлистинг (серый список)
  • Ошибки, связанные с неправильной настройкой доменной почты
  • Попадание IP-адреса в черный список

Чтобы быстро найти значение вашей ошибки в статье, воспользуйтесь поиском по странице (ctrl+F). Для этого введите значение ошибки, как показано в слайдере ниже:

Ссылка на это место страницы:
#incorrect_address

Примеры ошибок:

  • Mailbox does not exist. We do not relay
  • No such user!
  • Unknown user
  • Recipient address rejected: User unknown in local recipient table
  • The email account that you tried to reach does not exist
  • sorry, no mailbox here by that name
  • no mailbox by that name is currently available
  • Requested action not taken: mailbox unavailable
  • Message was not accepted — invalid mailbox
  • Bad recipient address syntax
  • Bad address mailbox syntax
  • No correct recipients
  • We do not relay without RFC2554 authentication

Рекомендации:
Попробуйте связаться с получателем альтернативным способом связи, чтобы уточнить корректный электронный адрес. Затем поменяйте email в карточке. Как это сделать, смотрите в слайдере:

  • MX lookup failed for […]

Данная ошибка указывает на проблемы с MX-записью домена, на который отправлялось письмо, либо по каким-то причинам не удалось проверить его MX-запись. Возможно, при регистрации пользователь указал некорректный адрес почты. Повторные попытки отправки сообщений при получении данной ошибки не производятся.

Если не удалось связаться с почтовым сервером, то вернутся следующие ошибки:

  • Called MAIL FROM without being connected
  • SMTP connect() failed
  • RCPT TO command failed

Причины и рекомендации:

  • Опечатки в электронных адресах
  • Ограничения со стороны корпоративных доменов
  • Общие рекомендации по базе электронных адресов

Ссылка на это место страницы:
#errors

При регистрации пользователь может указать электронный адрес с опечаткой. Сообщение на такой адрес доставить не получиться. Наиболее часто встречающимися опечатками являются:

  • mail.ri — вместо mail.ru
  • gmail.ru — вместо gmail.com
  • yndex.ru — вместо yandex.ru

Рекомендации:

Периодически проверять базу пользователей на опечатки в электронных адресах и менять им почту.

Обратите внимание: электронная почта пользователя указана корректно, если она подтверждена. То есть чем больше % пользователей в вашей клиентской базе, которые подтвердили свою почту, тем меньше будет ошибок в адресах при отправке рассылок «по адресам, где дано разрешение на рассылки». И соответственно, выше доставляемость сообщений.

Ссылка на это место страницы:
#corp

Корпоративные ящики — это почтовые ящики с доменами, принадлежащими университетам, магазинам, государственным предприятиям и предназначенные только для их сотрудников. Например, @hh.ru.

Корпоративные ящики чаще всего имеют свои почтовые сервера, индивидуальные спам-фильтры или другие настройки, которые могут влиять на доставляемость сообщений.

Рекомендации:

  • Самостоятельно связаться с владельцами корпоративного домена, привести пример ошибки и уточнить, почему ваши сообщения не принимаются.
  • Если пользователей с таким доменом в аккаунте немного, то наиболее оптимальным решением будет узнать у пользователя альтернативную почту на более популярном сервисе (gmail.com, yandex.ru, mail.ru) и сменить ее в карточке пользователя.

Ссылка на это место страницы:
#popular

В качестве электронных почт пользователей рекомендуем использовать наиболее популярные почтовые сервисы, такие как mail.ru, gmail.com или yandex.ru. Это очень распространённые и надёжные почтовые сервисы с высокой доставляемостью сообщений.

Важно: Для снижения рисков попадания рассылок в спам отправляйте рассылки «по адресам, где дано разрешение на рассылки». Такие пользователи предоставили прямое согласие на получение рассылок, а их адреса точно не содержат ошибок. Поэтому важно не только собирать базу качественных электронных адресов, но и подтверждать их с помощью письма DOI.

Ссылка на это место страницы:
#temp

Также не рекомендуем использовать в качестве электронных адресов временные почтовые ящики. Временный ящик — ящик, который не требует регистрации и позволяет принимать электронные письма, которые будут удалены через определенный срок. Например, @yopmail.com или @maildrop.cc.

Как правило, такие ящики обладают рядом ограничений. Например, могут не поддерживать html-версию письма или не восприниматься почтовыми службами как надежные получатели, так как не принадлежат реальным пользователям. Поэтому отправка на них рассылок может привести к снижению репутации отправителя, а, следовательно, снизить доставляемость ваших сообщений.

Важно: вход во временные ящики осуществляется без пароля, поэтому их содержимое может просмотреть любой пользователь. Подобные электронные почты не рекомендуется использовать в качестве почт пользователей и сотрудникам (например, для тестирования).

Рекомендации:

Отписывать от рассылок или удалять из базы пользователей с временными почтами.

Ссылка на это место страницы:
#overflowing_box

Примеры ошибок, возвращающихся при отправке на переполненные ящики:

  • Mailbox size limit exceeded.
  • Mailbox size exceeded
  • User is overquota
  • The email account that you tried to reach is over quota

Примеры ошибок, возвращающихся при отправке на заблокированные ящики:

  • Mailbox […] is locked due to inactivity for more than […] months
  • Аccess to this account (user) […] is disabled
  • Mailbox is disabled

Причины:

Подобные ошибки означают, что в почтовом ящике получателя нет места, чтобы принять ваше сообщение. Чаще всего это происходит потому, что получатель редко пользуется ящиком и ящик переполняется рассылками. Подобные адреса также могут быть преобразованы в спам-ловушки, отправка на которые приводит к значительному ухудшению репутации отправителя.

Ссылка на это место страницы:
#disabled

Рекомендации:

Попробуйте связаться с получателем альтернативным способом связи и сообщить о проблеме. Если связаться не удается, вы можете отписать пользователя от получения рассылок. Рекомендуется периодически отписывать от рассылок пользователей, которые не читают ваших сообщений.

Ссылка на это место страницы:
#spam

Примеры попадания в спам:

  • IP […] Our system has detected an unusual rate of unsolicited mail originating from your IP address. To protect our users from spam, mail sent from your IP address has been temporarily rate limited — такая ошибка возвращается почтовым сервисом Gmail в случае если Google заподозрил отправку слишком большого числа подозрительных писем (спама) с IP адреса отправителя. В этом случае Google включает временное ограничение на количество принимаемых писем.
  • Message rejected under suspicion of SPAM
  • Client host […] blocked using spamsource.mail.yandex.net
  • Blocked by spam statistics
  • 550 spam message discarded/rejected

Причины:

При отправке сообщений из аккаунта вероятнее всего не были соблюдены рекомендации для высокой доставляемости. Например, не производился прогрев отправляющего домена или велись рассылки по базе пользователей, которые не давали своего согласия на их получения.

Ссылка на это место страницы:
#graylisting

Примеры ошибок:

  • Greylisting in action, please come back later
  • Greylisted, try again after some time
  • Greylisted, try again in 180 seconds
  • Sorry, the service is currently unavailable. Please come back later
  • Temporary local problem — please try later
  • Try again later

Грейслистинг (серые списки) — это способ автоматической блокировки спама. Принцип работы данного способа заключается в следующем: если почтовому сервису кажется подозрительным принимаемое им письмо, то он может не принять его и попросить переотправить сообщение позже.

Рекомендации:

На платформе GetCourse подобные запроса распознаются и письмо переотправляется автоматически позже. Спамерское программное обеспечение в таких случаях, обычно, не пытается переотправить письмо, и их сообщения не доходят.

Однако если письмо после 5 попыток переотправки снова вернулось с ошибкой, система фиксирует текст ошибки и больше не делает попыток переотправки. В этом случае письмо можно переотправить через некоторое время вручную.

Ссылка на это место страницы:
#mail_settings

  • non-local sender verification failed — обычно такая ошибка возвращается почтовым сервисом Gmail или Mail.ru. При появлении данной ошибки необходимо проверить корректность SPF, DKIM и MX в DNS-зоне домена, с которого осуществляется отправка рассылок.
  • Can’t verify […] sender. Check your DNS configuration — при появлении данной ошибки необходимо проверить корректность SPF и DKIM в DNS-зоне домена, с которого происходит отправка почты.
  • sender domain SPF exact match mandatory for IP […]— ошибка в SPF-записи домена, с которого происходит отправка письма. Необходимо проверить корректность SPF-записи, или что присутствует только одна SPF-запись.
  • This message was not accepted due to domain […] owner DMARC policy (RFC 7489) — сообщение было заблокировано из-за строгой политики DMARC почтового сервиса. Подробнее о настройке DMARC на GetCourse, читайте в отдельной статье.

For me it was too many emails per second:

...
SMTP -> FROM SERVER:XXX.XX.XX.X Ok
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> get_lines(): $data is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> FROM SERVER:XXX.XX.XX.X Requested action not taken: too many emails per second
SMTP -> ERROR: DATA command not accepted from server: 550 5.7.0 Requested action not taken: too many emails per second
...

Thus I got to know what was the exact issue.

I was experiencing this same problem. In my instance the send mail was timing out because my Exchange server was relaying email to a server on the internet. That server had exceeded it’s bandwidth quota. Apparently php mailer has some built in timeout and it wasn’t long enough to see the actual message.

If you are using the Office 365 SMTP gateway then «SMTP Error: data not accepted.» is the response you will get if the mailbox is full (even if you are just sending from it).

Try deleting some messages out of the mailbox.

In my case the problem was with the content of mail. When I changed content to simpler content without HTML, it worked. But after updating the phpmailer everything solved.

in my case I was using AWS SES and I had to verify both «FromEmail» and «Recipient». Once done that I could send without problems.

Mailgun sanbox error

With $PHPMailer->SMTPDebug = true; I found out that when using the mailgun sandbox domain, the email has to be added to an authorized recipients list (which is on the right panel of the sandbox domain overview)

It happen too, when you used stripslashes or addslashesh or real_escape_string.

Avoid these things inside email body, when your email execution code completed then you can add these lines in bottom.

I’ve been trying for hours to get PHP Mailer to work, but I keep getting;

2018-03-06 10:18:28 SMTP ERROR: DATA END command failed: 550 This message was classified as SPAM and may not be delivered
SMTP Error: data not accepted.
Message could not be sent. Mailer Error: SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: This message was classified as SPAM and may not be delivered SMTP code: 550

This is the code I am using to send the email through my sites mail thingy.

require '../ipn/PHPMailer-master/src/Exception.php';
require '../ipn/PHPMailer-master/src/PHPMailer.php';
require '../ipn/PHPMailer-master/src/SMTP.php';

$mail = new PHPMailer(true);                              // Passing `true` enables exceptions
try {
    //Server settings
    $mail->SMTPDebug = 2;                                 // Enable verbose debug output
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'mail.site.pw';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'magnolia@site.pw';                 // SMTP username
    $mail->Password = 'removed';                           // SMTP password
    $mail->SMTPSecure = 'ssl';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 465;                                    // TCP port to connect to
    
    $mail->setFrom('magnolia@antrax.pw');
    $mail->addAddress('lunasityboi@gmail.com');               // Name is optional
    
    //Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}

This is what I get from debugging;

Website sending email

I am trying to get my website to send out emails.

We have our domain registered at godaddy and the website is hosted at a2. we use o365 for email.

Before we switched to o365 when someone would place an order an email would go out to the customer. Since we switched the emails fail. I added an spf record with the a2 server ip address and added a connector in o365. i set in the website cpanel for remote email

This is the error I am getting

«ErrorMessage could not be sent.
Mailer Error: SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: 5.7.60 SMTP; Client does not have permissions to send as this sender [BN6PR11MB1857.namprd11.prod.outlook.com] SMTP code: 550 «

Is there a send on behalf of setting on your email account that you need to add permissions to?

Is there any need to relay through O365? Why not send directly from the web server after defining the SPF record?

This link might help you as well.

dont understand what you mean «send on behalf of» . The website is acting like an email client and sending out the emails using o365 credentials. Where would i add permissions for that?

I am using method one. Its the only one that i have the option for. i posted a picture of my possible settings that i have available. I guess I can use a different smtp server if I setup an address somewhere but not sure where I would find one that works.

my spf record looks like this v=spf1 ip4:00.00.00.00 include:spf.protection.outlook.com

all . i have in there the correct ip of the a2 server that is hosting the site.

Make sure you are using the SMTP server listed in the technote — different O365 SMTP servers allow different things.

I have tried both smtp.outlook.com and outlook.office365.com. both give the error

The user account you are using is a licensed account and not a shared mailbox?

Only other thing I can think of is the «from» field in the email itself doesn’t match the user account account being used to login to the smtp server.

What «connector» did you add on the O365 end — you don’t need one using Method 1 so that might be an issue.

Let me check the email send from field.

I setup the connector based on o365 support that sometimes it helps even for method one

  • check 174 Best Answers

I think for the connector to even come into play, you need to use your O365 MX record for the SMTP server — yourdomain-com.mail.protection.outlook.com, etc.

As noted you do not need a separate connector if you are authenticating with an account, it is useless. If you needed an anonymous IP restricted send, then you would use a separate connector.

I’m agree with you mate.

I am now getting this error after i made the from field match the authenticating email
