Sorry...I've completely forgot to use login username as firstname.lastname@example.org
But now my syslog says:
Jan 7 11:54:57 lintvern courierpop3login: Connection, ip=[::ffff:184.108.40.206]
Jan 7 11:54:57 lintvern courierpop3login: chdir "home/vmail": No such file or directory
Anyway, I have another question. What if someone sends e-mail to root or some other users from /etc/aliases. Should I put all users from /etc/aliases to forwardings table?
