I ran into a problem, I'm trying to set up postfix mail server (I'm using webmin), everything seems to work fine, I successfully connected outlook to POP3/SMTP, but as soon as I send an email, it gets stuck in postfix mail queue, only errors I see are in messages log file:

Jun 26 22:56:23 cloudlix saslauthd[23271]: do_auth : auth failure: [user=shop] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error]
P.S If I try to flush mail queue - nothing happens.
