Hosting a Mail Server at Home

I’m using NixOS since over a year for most of my server stuff and I’m loving it. One of the missing services was my email setup, originally deployed on Debian 10, later upgraded to Debian 11. I followed a setup guide and was quite happy, tweaking it over the years to my needs. Roughly, the software stack consists of Postfix as the MTA (“SMTP server”), Dovecot as the MDA (“IMAP server”) and rspamd including its requirement, redis, for spam protection and SPF/DKIM/DMARC verification as well as DKIM signing for outgoing mail. I avoided a webmail service to keep things simple and I already use standard mail clients across my personal devices anyway.
