I apologize as I know its is somewhat off topic. 

 

I have a postfix server running saslauthd 2.1.19 (cyrus-sasl-2.1.19-14) and
recently I have been hit with a lot of dictionary attacks using sasl
authentication.

While looking at this issue I noticed that the sasl logs,
(/var/log/messages) is not logging the remote ip of the failed attempt. 

 

[r...@mrelay3 deferred]# tail -f /var/log/messages

May 24 11:17:33 mrelay3 smtp(pam_unix)[23505]: check pass; user unknown

May 24 11:17:33 mrelay3 smtp(pam_unix)[23505]: authentication failure;
logname= uid=0 euid=0 tty= ruser= rhost=

May 24 11:17:35 mrelay3 saslauthd[23505]: do_auth         : auth failure:
[user=freedo] [service=smtp] [realm=] [mech=pam] [reason=PAM auth error

 

What can I do to have the remote ip show up on the logs. I have looked on
this lists archives and searched google but found nothing.

 

Thanks paul.
