It doesn't matter if there are other sites/services hosted on the same
machine/address; fail2ban works on patterns matching in logfiles; if
you only want to look at Mailman errors, only configure fail2ban to
look at the Mailman (vhost) logs.

If you've got (brute force attempt) issues from one host / botnet,
preventing access to other things, is surely an added win?
