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 firewalld problems with current CentOS 7
Hi!
I have a server running CentOS 7.7 (1908) with all current patches installed.
I think this server should be a quite standard installation with no specialities
On this server I have fail2ban with an apache and openvpn configuration.
I'm using firewalld to manage the firewall rules.
Fail2an is configured to use firewalld:

fail2ban ban not working
I have fail2ban on my mail server monitoring Dovecot and Exim.
I have noticed that it has stopped banning IP's. I have seen in /var/log/fail2ban.log:

Nasty Fail2Ban update for Centos 7
Hi all...
Recently a new Fail2Ban was available among some other updates for my
Centos 7 system, and I just updated all.
It seems that was a very BAD idea.
Just noticed that Fail2Ban have generated a 6MB error log because
of the update, and FirewallD a 1MB log of errors !
(not sure if any of those were really working after this)
ok, I'll just run yum downgrade fail2ban I thought.
Naa, no

SpamAssassin vs. SELinux
Hi,
I just installed SpamAssassin on two servers running CentOS 7 and
Postfix. One is my sandbox server for experimenting, the other one is
the server that hosts my company's web site, blog, mail, etc.
So far, SpamAssassin seems to work as expected. I sent a test mail,
which was duly flagges as [SPAM], and I already see the odd incoming
spam message correctly flagged as [SPAM].
