Backup MX for Mailman, with Exim

This week a hard disk from one of my servers broke. It has been replaced with just 3 minutes of downtime (kudos to OVH), and right now the RAID array is being rebuilt.

Since this is the first time this happens to me, and the server is running a production mailman service, I decided to take my time and set-up a backup MX server. This is how I did it.

Gentoo: How to debug Exim

If you have some problem with exim, and the logs are not enough, edit the /etc/conf.d/exim file, and add the debugging option (-d):

/etc/conf.d/exim
# Command-line options for running exim
EXIM_OPTS="-bd -q15m -d"

Then restart exim:

# /etc/init.d/exim restart

The exim daemon will not be detached from the console, the debug information will be printed to the standard output. Good luck!
