I got it up and running in a tiny LXC (Debian 13, 2G RAM, 1CPU and 4G disk), took about 10 minutes So far, it looks solid, I am yet to enable JMAP and I'm not sure I really need it for a POC. The "Enterprise" options (Tenants, AI stuff, ...etc,) are not really crippling it, https://stalw.art/compare/ I am still trying to figure out how to setup SMTP relays, and if there is a way to run fetchmail natively a la Mailcow. Any questions or test requests, let me know -nick On Mon, Jan 12, 2026 at 10:16 PM Ron via Talk <talk@lists.gtalug.org> wrote:

I want to hear about this too. My entire email usage depends on Dovecot, and Dovecot 2.4.x has jumped the shark in order to offer a proprietary product not in competition with their free software
What changes are you referring to?
I've just looked over this page:
https://doc.dovecot.org/main/installation/upgrade/2.3-to-2.4.html#removed-fe...
and I'm seeing some things I like, some I don't know about, some that may bite me, but nothing about removing features that I use.
Global ACLs are a PITA, and they're changing how to implement ACLs, so the ability isn't gone, just different.
IMAP SETQUOTA is going away, but user_db / pass_db (userdb_quota_rule=) is where I set those anyway. Don't think it'll affect me?
The "Backends and Plugins" section will require careful parsing at some point.
