I have installed iRedMail without problems. I can’t send and recieve mails.

My DNS configuration is:

When trying to send a mail from gmail:

Delivery to the following recipient failed permanently:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain by [2607:f8b0:4003:c08::1a].

The error that the other server returned was:

  • Maybe there is a problem with my /etc/hosts file?

    root@main:~# cat /etc/hosts   localhost.localdomain   localhost main main

It looks like you have Gmail’s MX records on your domain name. Do you have a Google Apps account? If not, you should remove the MX records and keep only the ones that point to your iRedMail droplet.

  • It didn’t solved my problem. I made changes in my DNS records and now when im sending an email from gmail to my server it shows:

    Final-Recipient: rfc822;
    Original-Recipient: rfc822;
    Action: failed
    Status: 4.4.1
    Diagnostic-Code: X-Postfix; connect to[]:10024: Connection
