Migrated to Ubuntu 26.04 and the Debian mailman packages as they now seem to be on the same version of Mailman as I came from previously which means a bit less effort for maintain the system. Also migrated to Postfix as we can do the configuration of the whole system in around 10 Postconf commands which is easy to script. Hoping everything working ok.
Yes so far. I moved to Postfix from Sendmail a number of years ago and never regretted it. It still hosts one of my email addresses. My understanding is that Mailman 2 is no longer supported, and Mailman 3 is current. On the same account, I'm using Rspamd for spam filtering and Dovecot for allowing IMAP access. Crowdsec takes care of blocking a variety of attacks from the world's criminal fraudsters etc. I'm still running Bind 9 for the DNS authoritative name server. DNSSec, DANE, SPF, DKIM and DMARC are all set up. Obviously, it's entirely a matter of configuration file editing, hence no accessibility issues whatsoever.
