[GTALUG] Testing Stalwart email server: replacement for postfix / dovecot / etc.

I've been giving this https://Stalw.art email server software a test and it's *slick*. I like that users can set their own passwords without me having to provide RoundCube (PHP + ... + ... + plugin for RoundCube). It also allows users to enable at-rest encryption. Supports CalDAV / CardDAV / WebDAV out of the box. Supports SMTP / IMAP / POP / JMAP. Supports OAuth and OpenID Connect. I haven't been able to test all the features, but am quite pleased with what I've seen so far. Providing email with calendar and contact support without needing postfix / dovecot / opendkim / Nextcloud / PHP / Redis / ... is really sweet. If anyone wants an email account to try for themselves, let me know.
