Can't receive emails to my mail server

  • 772

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 ([email protected]) to another ([email protected]) and i can read it as well, but when I send to email address of my email server ([email protected]), it sends, but I do not see it in inbox of [email protected]...

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...

  1. Best Answer

    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
}

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