I created a mail server, following this tutorial:
https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql ,

I configured the email on my email client, SMTP and IMAP and both connections are working, I can send email from my email address (example@domain.com) to another (example@gmail.com) and i can read it as well, but when I send to email address of my email server (example@domain.com), it sends, but I do not see it in inbox of example@domain.com...

Created a mx record: example.com mx 10 example.com
and created a spf record too: v=spf1 a mx ~all

The mail server is on Ubuntu 14.04.1 Desktop.

My question is: Why I see no inbox on email, if I send emails to it? I tried with POP3 too...

  • What does your mail log show when it receives a message? – NickW Jan 29 '15 at 15:27
  • Do you have the appropriate firewall rule(s) set up for inbound SMTP to your server? – joeqwerty Jan 29 '15 at 15:29
  • @joeqwerty Are you asking if I have iptables setup? I have no iptables configured yet. – DiogoSaraiva Jan 29 '15 at 15:39
  • @NickW I updated my question please see above... thanks – DiogoSaraiva Jan 29 '15 at 15:41
  • iptables, network firewall, whatever. Does your firewall (host, network or otherwise) have the appropriate inbound rule(s) for inbound SMTP traffic to reach your server? Have you tried to telnet to your server from another machine on the LAN and from a machine on the internet? That's what I would suggest as a first step. – joeqwerty Jan 29 '15 at 15:44
  • @joeqwerty I don't know if you are question about this but here I go: I associated the SMTP SMTPS IMAP IMAPS POP POPS and LMTP (UDP and TCP ports) Ports to my server machine. This on my router... – DiogoSaraiva Jan 29 '15 at 15:54
  • For incoming Mail, the postfix config would be more interesting. Its not an iptables issue, as your server cr7akg.com is reachable via smtp from outside. Please mind, that running a mailserver is a quite complex task and without proper knowledge you'll end as spam relay quite fast. If you need a good to maintain email solution, which also runs without much postfix/dovecot knowledge have a look at iredmail. – Henrik Jan 29 '15 at 17:24

Found this solution:

add this on /etc/dovecot/conf.d/20-lmtp.conf: 

protocol lmtp {
postmaster_address = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf # required
mail_plugins = quota
}

probably this was:

protocol lmtp {
  # Space separated list of plugins to load (default is global mail_plugins).
  #mail_plugins = $mail_plugins
}

In my case I had a bad log path in my dovecot configs. Make sure you check your dovecot logs for possible errors.
