What goes for maillog my guess will be that You haven't installed

Check that out and if it's not installed, then install the package :

It seems to work. I'm also using the

fail2ban. That should catch attempts on imap and pop3, but I've

If you're smart, you're probably running 'fail2ban' (or something
similar) on your qmailtoaster to block password-guessing attempts. You
may also have used the rules given at:
http://wiki.qmailtoaster.com/index.php/Fail2Ban
to configure it.

Hi Dan.
It's always a good idea to test the filters I have learned - due to
differences in log entries - it is easy to check if Your filter will
catch what You want.
fail2ban-regex /path_to_log/logfile /path_to_filter/filter.conf
Example:
fail2ban-regex /var/log/maillog
This is very useful. Be sure your setup works before trusting/relying
on it.
