Re: [CentOS] Fail2ban mail failures ???
I'm using fail2ban with CentOS 6.6. Something is causing fail2ban's alerts sent to root's mail to be rejected. Here's a clip from one of the error messages: Message 48: From mailer-dae...@lion.protogeek.org Sun Dec 21 03:09:20 2014 Return-Path: Date: Sun, 21 Dec 2014 03:09:19 -0600 From: Mail Delivery Subsystem To: postmas...@lion.protogeek.org Content-Type: multipart/report; report-type=delivery-status; boundary="sBL97EKS003880.1419152959/lion.protogeek.org" Subject: Postmaster notify: see transcript for details Auto-Submitted: auto-generated (postmaster-notification) Status: R Part 1: The original message was received at Tue, 16 Dec 2014 03:09:17 -0600 from localhost with id sBG97E83025627 - The following addresses had permanent fatal errors - - Transcript of session follows - ... Deferred: Connection timed out with example.com. Message could not be delivered for 5 days Message will be deleted from queue .. I used to get the messages that are now being deleted after five days. Any suggestions? Check your /etc/fail2ban/jail.local /etc/fail2ban/jail.conf. You have to provide valid email addresses for dest= and sender= parameters in sendmail-whois or mail-whois actions for enabled jails. os.org/mailman/listinfo/centos Александр Кириллов, I should have made it clear that this is all on one machine. The jail.conf file is the default from the fail2ban package. It used to work perfectly, but now has the mail problem. All I've had to do for years is install the fail2ban package, start it, and make it autostart whenever I reboot. Now it's misbehaving in a way that puzzles me. Robert, If you never changed fail2ban defaults you probably had email aliases defined somewhere in your configurations. Whatever you had it was incorrect and it's not worth the effort to figure out why it ever worked if at all. The "right" way is to use email addresses in (at least locally) routable domains.
