I set up, following this tutorial

Postfix, dovecot and Squirrelmail. I can correctly send mails but I cannot receive. I can receive mail only if I send them by myself to myself.

This is a log sending to myself an email:

I have to admit that following the tutorial at Devcot installation did not followed the gui to set the autosigned ssl certificate so I did not set it, maybe depends on it?

UPD:

I have tested with pingtool and this is the result: Nmap scan report for mervo.io (185.14.185.89)

PORT STATE SERVICE
23/tcp filtered telnet
25/tcp filtered smtp
  • You set MX record for Your domain? port 25 (postfix/smtpd) is accessible from outside (try telnet or smtp client from external host or web tool like pingtool.org/#tab01)? Show log of external smtp session if any. – mmv-ru Mar 23 at 3:42

  • Regarding to DNS I have: No DMARC Record found, DNS Record not found ,DMARC Policy Not Enabled DMARC Quarantine/Reject policy not enabled – Stefano Maglione Mar 23 at 11:47
  • Better add important information in question body. – mmv-ru Mar 23 at 17:16

  1. You need open port 25 (with responding mail server on it). Probably it closed in ubuntu firewall or in worst case by ISP firewall.
  2. Initially You need MX rcord in Your domain pointing to IP of mail server, with open port 25. About SFP, DKIM, DMARK and etc, it more important for accepting mail from Your server by third party mail servers as not a spam. It next step of configuration, after success in basic functionality.
