Mail forwarding is not working on the server. The following error appeared in /var/log/maillog:

postfix/pipe[131455]: 47A161232DA: to=<second@odintest.tld>, relay=plesk_virtual, delay=0.03, delays=0.01/0/0/0.02, dsn=5.4.6, status=bounced (mail forwarding loop for second@odintest.tld)


Link /usr/sbin/sendmail has been replaced/deleted.


  1. Check if there a missing link:

    # ls -la /usr/sbin/sendmail
    lrwxrwxrwx 1 root root 21 Oct  3 01:15 /usr/sbin/sendmail
  2. If the link is missing create it using the following command:

    # ln -sf /etc/alternatives/mta /usr/sbin/sendmail

    After execution of aforementioned command it should look like the following:

    # ls -la /usr/sbin/sendmail
    lrwxrwxrwx 1 root root 21 Oct  3 02:15 /usr/sbin/sendmail -> /etc/alternatives/mta
  3. Restart postfix:

    # service postfix restart
