Email on Keldo.uk

Mail Server Down

Thu, 16 Jan 2025 00:00:00 +0000

It started when i tired to set up my emails on Thunderbird mail on arch I noticed it wouldn’t connect. I checked the logs and found “2025-01-16 21:04:11,919 WARN exited: amavis (exit status 1; not expected)” I fixed this relatively quickly by removing “amavisd.pid”. After this it booted but I still couldn’t connect.

I tracked this down by using dig and whats my ip to see that the dns record was wrong. I fixed this by switching to a cname record set to @ so i only need 1 ddns setup. This finally fixed it.

Docker Mailserver

Ever since I setup mailcow I have been annoyed that it runs with docker volumes and updates with a script. This makes it imposible to run how I want. I feel the main benefit of docker should be all the files needed are backed up and I can use the docker compose file to spin the container up anywhere.

I have tried may times to fix these problems in mailcow and have always failed. So I finally gave up with mailcow and started looking at other options. I quite quickly found docker mailserver as my main option. I don’t know if I didn’t see it the first time round or if I was scared of by the lack of a GUI. What ever the case now I am happy to use the command line for everything.

Broken mailcow

I began by trying to move my mailcow install from running on docker volumes to storing data on my nas. I started copying the files however after around the 5th volume I remembered the continers were still online. After I continued even finding a copy of the docker compose.

However when I ran the compose I got serveral errors about mysql. I realised I had corrupted the mysql database. I tried several edits to the mysql files and failed. After that I went to launch the old copy and realised that was corrupted as well.

Mailcow ssl

The first thing I noticed was wrong was that my Iphone was giving me a pop up telling me it could verify the identity of mail.keldo.uk. My first though was that the ssl cert had expired but as far as I knew Mailcow should automaticly refresh the cert. Luckily it was easy to debug as Mailcow has a nice selection of logs and I just open the acme logs and Imedialty saw the issue “mail.keldo.uk - Found AAAA record for mail.keldo.uk: 2a00:23c7:82c2:6401:be24:11ff:fe6d:10fa - skipping A record check” was apearing every hour. I setup ipv6 records when I set up mailcow however since I have a dynamic IP and haven’t set up a ddns for ipv6 it was seeing ipv6 skiping ipv4 and then seeing the ipv6 didn’t match. The simple solution was I just removed the ipv6 record and then the next hour it was fixed.

Mailcow Install

I decided I wanted to be able to get emails from my services as that is the mail method most of them support. For my mail server i decided to use mailcow rather than try to stitch together my own group of programs. The install was easy with no errors by simply just using a Docker compose file. Its smtp work fine with TrueNAS, Pterodactyl, Nextcloud, Proxmox and Passbolt however i could not get it working with Mealie.
