I solved a similar issue with jail and syslog adding a -a

From the syslogd man page:

I supose that you are using SMTP authentication with SASL.
From the log service=smtp...so, in fact, the attack is coming from
the SMTP server and not directly to the SASL.
I guess that someone is trying to do a brute force attack on the SMTP server.

In our environment the chroot jail is /home/username. Does this mean
we need a /home/username/dev/log for each and every user? If the

If you have:
/home/username01/[etc,dev,tmp,bin,lib]
/home/username02/[etc,dev,tmp,bin,lib]
/home/username03/[etc,dev,tmp,bin,lib]
/home/username04/[etc,dev,tmp,bin,lib]
I believe you will need:

There is a kernel option you can give to solve
this problem, in /boot/grub/grub.con add to the end
of the kernel line:
rootdelay Xs
where x is the amounty of time to wait before
/root is mounted, however this is valid for
everything else as well.
play with X until you get it right.

Yes... most of them. Just the new PITA. Anyway... I still can't seem to
figure out how to log the IP addresses for this attack.
The system is saslauthd running as a service... sendmail and dovecot
setup. I have log levels in sendmail set to 14. Something has to be able
to log the offender(s).
Perhaps you can use netstat to identify who is currently connected to
the machine. Then run it several times over a short period and block
the most likely culprits ?

I'd use iptables to log connections on that port and then time-correlate
with the log entries from saslauthd.
