I have just tried this, and re-started fail2ban. It does not seem to have worked.
I have looked at /var/log/exim/main.log and found

Dear collegues,
many thanks for your valuable input.
Since we are an university GEO-IP blocking is not an option for us.
Somestimes I think it should ;-)
My "mistake" was that I had just *one* fail2ban filter for both cases:
"wrong password" and "unknown user".
Now I have two distinct jails:
The first one just for "wrong password" and here the findtime,

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

CentOS 7 : SELinux trouble with Fail2ban
Hi,
Some time ago I had SELinux problems with Fail2ban. One of the users on this
list suggested that it might be due to the fact that I'm using a bone-headed
iptables script instead of FirewallD.
I've spent the past few weeks getting up to date with doing things in a more
orthodox manner. So currently my internet-facing CentOS server has a nicely
configured NetworkManager, and

fail2ban Asterisk 13.13.1
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+

fail2ban
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
