+ tl;dr - Host some Thunderbird autoconfig formatted XML, and text files at the right places (thanks to MTA-STS) so clients can have easy-peasy email setup. This was a fun chance to flex my Traefik installation, and kcup. You’re hosting your own email server right? Cool, me too. Good thing we ignored all the naysayers out there. In the past I’ve run postfix + dovecot setups and now I run many small maddy instances (for various projects), but I never looked into autoconfig.
