Okay, but how?
Thats working (but i get the IP not the user)
failregex = ^.*\[(?:::f{4,6}:)?(?P<host>\S+)\],
sasl.*sasl_username=(?P<USER>\S+)$
That's not working (no match)
failregex = ^.*\[(?:::f{4,6}:)?(?P<user>\S+)\],
sasl.*sasl_username=(?P<host>\S+)$
that one does not work too (no match)
failregex = ^.*\[(?:::f{4,6}:)?(?P<user>\S+)\], sasl.*sasl_username=<HOST>$
Example Logline:
Apr 13 15:09:27 mailgw postfix/smtpd[13276]: C247D2B:
client=exchange1.fhstp.local[10.0.1.5], sasl_method=LOGIN,
sasl_username=exchangemailer

Betreff: Re: [Fail2ban-users] Configure fail2ban to count usernames
You can't. Fail2ban can only use <HOST>. However, you can make <HOST> match the
user ;-) But it's one or the other, because you only have 1 variable to play
with.
