Problem with receiving email (ERROR 550: Recipient not found)

2016-04-28, 01:46 PM
It turns out that I used wrong MX records (smtp.secureserver.net) instead of mine. It came to me just after I answered to your post. I guess thanks for asking the right question

Hi scsa20, thanks for your reply.

The email server is self hosted on my vps. Postfix

That error is stating that there's no mailbox for zarun@oac-online.com. You use godaddy for your email service? If so which email plan? (basic email, exchange, office 365 email?)

Its not only with Gmail but with other SMTP server as well getting the same error.. Looks like the email address is not setup correctly.

First of all thanks for providing such a great service at affordable prices. Since this is my first post on the forum, I'd like to say that I'm really pleasantly satisfied with hosting on OVH.

Now the getting to point part.
I rented the VPS machine, and tried to setup services manually in order to use as low as possible process and memory resource on the machine.
I setup LAMP successfully, along with postfix and dovecot for mail server. My mail client successfully connects to the account and test message wents OK. However, it turns out that I can send email, but can't receive it from anyone else besides myself.

At first I thought it was something I did wrong with the manual configuration, so I did a clean VPS reinstall, and ran a Sentora automated package. This didn't resolve the problem:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain oac-online.com by smtp.secureserver.net. [].

The error that the other server returned was:
550 5.1.1  Recipient not found.  
So I went a step further, paying a closer attention to this error message, I figured it probably might have something to do with my MX records on the domain registar. My domain is registered at godaddy, and I didn't (find need to?) do DNS transfer to ovh.

Below is my domain configuration:

I changed MX records smtp.secureserver.net to smtp.europe.secureserver.net and mailstore1.secureserver.net to mailstore1.europe.secureserver.net but that din't do any difference either.

Now I'm running out of ideas. Any help would be appreciated.
