Error rcpt to not accepted from server opencart 3

Hello, we are using the amazing version OC 3.0.3.1 but We have a spam issue and we must use SMTP in email setting to reach our customers inbox

So my server is configured correctly regarding rDNS,SPF,DKIM and SMTP restriction. Also the parameter in mail setting inside OC setting is correct.

And we can send order status updates and newsletter successfully without any issue. But when try to place an order from front-end ( main website ) only not from back-end ( admin ) I received the following error

PHP Fatal error:  Uncaught Exception: Error: RCPT TO not accepted from server! in /home/***/public_html/storage/modification/system/library/mail/smtp.php:275
Stack trace:

#7 /home/***/public_html/vq in /home/***/public_html/storage/modification/system/library/mail/smtp.php on line 275

SMTP setting:
Mail Parameters: email@domain.com
SMTP Hostname: ssl://domain.com
SMTP Username: email@domain.com
PW: ******
port: 465

Also I tried tls and same result

Any Suggestion or support will be highly appreciated !!

It would be handy for you to post a link to the topic you have in mind?

So … suggesting one that solves the problem would be very helpful to the OP

There might be different solutions and I’m not sure which one suits the case.

Try switching to mail? your smtp details are likely incorrect

thanks for your reply all unsecured emails going to spam or not delivered and must use SMTP also for security reason as our email used for spoofing and reply to from a spammer and that’s why our emails going to spam now

This question been asked multiple times. Search forums for «RCPT TO not accepted».

thanks for your reply, I searched all the forums here and github and a lot of others forums, but this is a different issue Order Updates email sent with no problem, only order confirmation email have the issue which approve that smtp is correct.

Thanks for sharing this solution, but it have no relation with our issue as our contact form working well, all and everything is working fine with smtp except order confirmation email !! that’s why I opened a new topic.

This is a generic issue, related to any kind of mailing functionality. To figure out, if particular solution is helpful you need to actually try it. Did you?

Thanks for your reply, I really doubt you even read my post you just may be see the subject and start being aggressive.
Whatever I appreciate your involvement in supporting solving my issue, but this solution was for OC 1.5 and I’m talking about is OC 3.0.3.1 which is using another concept of coding.

and the solution there in that post can’t be implemented on OC 3 as there is now such a code in the file and I try it by the way from couple of days when I saw this solution

The code is instead in:

catalog/controller/information/contact.php

But in OC3 it is already:

$mail->setFrom($this->config->get('config_email'));
$mail->setReplyTo($this->request->post['email']);

So unfortunately this isn’t a solution in OC3 … but did you try the solutions from the 2 other articles I posted?

Apparently you have no idea what you’re talking about. And we’re talking about GENERIC PHPMailer issue, which you can search in google for and see, that it’s not only OpenCart related. I’m not trying to be aggressive, I’m telling you that this issue has been mentioned and EXPLAINED multiple times even on these forums. And if you also search in Google, you will find more solutions with pretty good explanations of what is going on.

This only proves my point above: you don’t have enough experience and don’t actually understand the issue. And Paul’s reply below tells you the same. You’re looking for exact code pieces and, of course, you’re not finding anything. This is why you need to UNDERSTAND the issue — then you will be able to find a solution. Otherwise be ready to pay for someone to do this for you.

Alright let’s all play nicely

How about those other 2 articles, they seemed to have quite good step by step instructions?

Hello Paul, first article I found it in my first search and still didn’t solve the issue.
Second article I didn’t see it before, so I read it now and will try it tomorrow if it will work

thanks for your support
