I use SSHGuard on well ssh (doh!), but supposedly you can use it for postfix and dovecot also. I can tell you it is well supported. I am on Centos 7 using firewalld. ? Original Message ?

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 [root at mail ~]# ls -l /etc/fail2ban/filter.d/doveco* -rw-r--r-- 1 root root 1875 May 11 2017 /etc/fail2ban/filter.d/dovecot.conf [root at mail ~]#

I'm trying to set up fail2ban with dovecot, I have it working on 'old' server Centos 6, but, not getting anywhere with 'new' server on Centos 7 using standard filters I've copied same 'filter' to new server, still get nothing any idea how to figure this out ? on old server, it logs to syslog/messages CentOS release 6.10 (Final) dovecot 2.3.10.1 (a3d0e1171) old #

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: # fail2ban-client status dovecot-pop3imap Status for the jail: dovecot-pop3imap |- Filter | |- Currently failed: 0 | |- Total failed: 0 | `- File

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there

Hello Anyone have a working copy of Fail2ban asterisk filter asterisk.conf for Asterisk 16 running PJSIP. I have tried 10 different filters but none of them show any matches when testing with fail2ban-regex I see date template hits but no matches....

I'm currently using postfix and dovecot, with dovecot authentication (with saslauthd) using mysql for accounts Is there any option available for me to help inhibit/prevent brute-force login attempts? Thx. Rick Rick Steeves http://www.sinister.net "The journey is the destination"

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 filter.d/dovecot.conf [Definition]

Hello list. I have a question for fail2ban for bad logins on sasl. I use sasl, sendmail and cyrus-imapd. In jail.conf I use the following syntax: [sasl-iptables] enabled = true filter = sasl backend = polling action = iptables[name=sasl, port=smtp, protocol=tcp] sendmail-whois[name=sasl, dest=my at email] logpath = /var/log/maillog maxretry = 6 and the following filter:

Hi, mail_max_userip_connections is only enforced at the backend level. The setting has no effect on proxy. If you want to force the limit then you can only do it in the backend.

I have turned on 'auth_debug_passwords=yes? in dovecot.conf.

Yes, multiple imap servers using one shared nfs storage. With the same config on 2.2.13 the public interface traffic was similar to the storage interface, around 100 mbps. After we switch to 2.2.27 the storage interface traffic jumped 10 times while the public interface stayed the same. This make us thinking that something is wrong and each time a user logs in the whole Inbox content is read
