I'm trying to setup and test fail2ban with dovecot
I've installed fail2ban, I've copied config from
https://wiki2.dovecot.org/HowTo/Fail2Ban, and, trying to test it,
attempted multiple mail access with wrong password, but, get this:

service fail2ban restart

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

no, not in jail.conf, I've put it in the

/etc/fail2ban/jail.local
I've also added postfix, that seems to work:

If this is a small site, I recommend you download the free version of SecAst
(www.telium.ca <http://www.telium.ca> ) and replace fail2ban. SecAst does
NOT use the log file, or regexes, to match etc.instead it talks to Asterisk
through the AMI to extract security information. Messing with regexes is a
losing battle, and the lag in reading logs can allow an attacker 100+

For dovecot 2.1
as per wiki2, is this still valid? noticed a problem before and saw
it does seem to be triggering, I use:
maxretry = 6
findtime = 600
bantime = 3600
and there was like, 2400 hits in 4 minutes, it is pointing to the
correct log file, but I am no expert with fail2ban, so not sure if the
log format of today is compatible with the wiki2 entry

Editing fail2ban page?
In https://wiki.dovecot.org/HowTo/Fail2Ban, for a current (I know for
a fact in 2.2.36) I believe it should be
filter = dovecot
instead of
filter = dovecot-pop3imap
