Hi at all,

I have some entry in log on the my mailserver (with installed ossec agent)
like this:

Oct 31 12:03:15 mailscanner04 dovecot: pop3-login: Disconnected (auth
failed, 1 attempts): user=<***@caccabee.it>, method=PLAIN,
rip=222.252.6.70, lip=10.12.14.36

and my ossec server in the alert.log say:

Oct 31 12:03:15 mailscanner04 dovecot: pop3-login: Disconnected (auth
failed, 1 attempts): user=<***@caccabee.it>, method=PLAIN,
rip=222.252.6.70, lip=10.12.14.36

** Alert 1540983795.5645464: mail -
dovecot,invalid_login,authentication_failed,
2018 Oct 31 12:03:15 (mailscanner04.tech2.it) 10.12.14.36->/var/log/messages
Rule: 9705 (level 7) -> 'Dovecot Invalid User Login Attempt.'
Oct 31 12:03:15 mailscanner04 dovecot: pop3-login: Disconnected (auth
failed, 1 attempts): user=<***@caccabee.it>, method=PLAIN,
rip=222.252.6.70, lip=10.12.14.36

The problem is: rules 9705 in the dovecot rules have level 7 and in my
ossec.conf all rules over level 6 trigger a active response.. but not for
'dovecot'.. I don't understand why..
All AR working fine for ALL other rule.. http and smtp.. only for dovecot
don't trigger a active response..

Any suggest are appreciate.
