People, I have wanted to get my old QMail mail server system up to date for some years (it has been going more-or-less unchanged for about 21 years!). Some years ago I started using docker for my Jekyll and Rails sites and more recently I became quite interested in Podman - which I thought was a much nicer environment for me - I used RH from version 4.0 to 9.0 (before RHEL came on the scene) and have been using Fedora since the beginning - so the whole environment was very interesting for me - as well as for Atomic, CoreOS and SilverBlue etc. I became interested in IndiMail: http://www.indimail.org a while ago because it was a well maintained and enhanced version of QMail with everything you would need in a modern MTA. So as time went on it seemed natural to think of moving over to IndiMail but having it running in a Podman container. Anyway, after a lot of time spent both by me and Indimail creator, Manvendra, and with the generous help of people on this list, we have finally gotten the "light" version, IndiMail-MTA, working. A quick summary of the current situation: 1. I install the image with: podman pull cprogrammer/indimail:fc31 2. I create a container with: podman run -d -h pricom.com.au \ -v /home:/home \ --net=host \ --name $imv \ `podman images | grep "$imv" | awk '{ print $3 }'` \ $imv 3. Make manual changes to stuff in /etc to correspond to the users in the mounted /home dir - soon I will look at the previous suggestions from people here to see if I can make that situation nicer. There are some domain specific changes that need to be made to the files in: /etc/indimail/control We had to make some changes to the SMTP setup so it could talk to RoundCubeMail - RCM was attempting to try the last AUTH SMTP method advertised (DIGEST-MD5) instead of AUTH PLAIN or AUTH LOGIN. The unconfigured AUTH methods were disabled by setting env variables in the SMTP config. As of now, I think it is a pretty seamless process to get up and running. The light -mta version is quite adequate for my needs but the full indimail install can handle lots of domains, millions of users and very high volumes of mail - and it is very fast ie it has kept all the features that the original QMail was popular for but has all the enhancements needed for a modern mail server. As we move from F31 to F32 and future versions, I will streamline my process for pulling the image, building the container and making custom changes. I will also, start building from the Docker files and, at some stage when I have more time, repeat the exercise with the full IndiMail suite to also get that going painlessly.
