under another kind of attack

[Davide Marchi]

Hi to all,

@Olaf Hopp I've this filter enabled for fail2ban, my question is: could 
my filters overlap or interfere with those suggested by you?

this is my filter:


Contents of /etc/fail2ban/jail.conf:

[postfix]
# Ban for 10 minutes if it fails 6 times within 10 minutes
enabled  = true
port     = smtp,ssmtp
filter   = postfix
logpath  = /var/log/mail.log
maxretry = 6
bantime  = 600
findtime = 600

Contents of /etc/fail2ban/filter.d/postfix.conf:

# Fail2Ban configuration file
# Author: Cyril Jaquier
# $Revision$

[Definition]

# Option:  failregex
# Notes.:  regex to match the password failures messages in the 
logfile. The
#          host must be matched by a group named "host". The tag 
"<HOST>" can
#          be used for standard IP/hostname matching and is only an 
alias for
#          (?:::f{4,6}:)?(?P<host>[\w\-.^_]+)
# Values:  TEXT
#

# Jul 11 02:35:08 mail postfix/smtpd[16299]: lost connection after AUTH 
from unknown[196.12.178.73]

failregex = lost connection after AUTH from unknown\[<HOST>\]

# Option:  ignoreregex
# Notes.:  regex to ignore. If this regex matches, the line is ignored.
# Values:  TEXT
#
ignoreregex =


Many thanks!
