cannot receive email on ubuntu email server

  • 772

I setup the email server. I am able to send out mail but when I try to receive mail by sending an email to myself from another email, it doesn't work. The other email I receive a mailer-daemon and this one shows as a reject.

This is the error that i get in (/var/log/mail.log):

Jun 24 19:17:31 localhost postfix/smtpd[13352]: connect from mail-lb0-f173.google.com[209.85.217.173]

  1. The following line from the error log gives valuable info:

    localhost postfix/smtpd[13352]: NOQUEUE: reject: RCPT from mail-lb0-f173.google.com[209.85.217.173]: 550 5.1.1 <[email protected]>: Recipient address ejected: User unknown in local recipient table; from=<[email protected]> o=<[email protected]> proto=ESMTP helo=<mail-lb0-f173.google.com>

    Postfix should relay all mail to other servers on the internet, it does not actually receive mail for any domains. As in the error log example.com should be forwarded to the mail server for example.com. The solution, is to remove $mydomain from postfix config /etc/postfix/main.cf in line:

    mydestination = $mydomain, localhost.$mydomain, localhost

  2. For me, the issue was that I also had a DNS issue. To fix this, I used 

     dpkg-reconfigure postfix

    From within the terminal window and changed the "local networks" field answer to include the IP of my public IP for the server.

    Afterwards, I ran service postfix reload and service postfix restart and all was well.
