When migrating #dovecot to a new server running #debian #trixie, no one told me that with dovecot 2.4.0 basically the whole configuration logic changed and that you need to completely re-write your config.
@Billie Ouch! And such "breaking change" was not warned about?!? Oof…
@IzzyOnDroid @Billie here is a tool that can maybe hell: https://dovecot.org/upgrader/

@ErikDerBezwinger even more hell? 🙈 Thanks, might even be "help" 🤪 @Billie

I won't edit the text. Everyone needs fun.

When upgrading you get warned. When you do a fresh install probably not, as there are no old configs anyway.
