Thanks to @darix and @cmouse !

Just announce my project #wormhole for #Dovecot on the dovecot users list:
https://dovecot.org/mailman3/archives/list/dovecot@dovecot.org/thread/YSLZ6T5S2YNH7TUT3BZHMRGXROQWCR3V/
Let's see if I get some feedback on it.
For more details about #wormhole see it's website on my homepage: https://people.mpi-klsb.mpg.de/~pcernko/wormhole.shtml

If you are creating a new #mailserver and you need to migrate mailbox files to mail directories. How would you do it?

We are using #dovecot on both machines and want to try to migrate to #mailcow.

what #disroot, #systemli, and #riseup did that made me build a similar collective. currently running some services under #openbsd from #indonesia:

• #prosody (#xmpp server)
• #dovecot, #opensmtpd, #rspamd (email server)
• openbsd environemnt (through ssh)
• nginx (web server)
• #unbound, #nsd (#dns server)

but, i ponder what i must do to pass the #security and perfomance standard.

can someone answer my question? i appreciate it so much

If I could choose one piece of technology that never let me down, that'd be Dovecot.

Their replication works amazingly. As soon as a server gets back online, all e-mail is synchronized back from the backup MX.

That kind of peace of mind is priceless.

I really want to update a server to Debian 13 "trixie", but Dovecot was updated to a version with incompatible configuration format.

Weekend plans, I suppose...

@delta

I was expecting this page to tell me if #Dovecot was supported..

@oldperl Jetzt schaut's wieder ok aus. Login/senden/empfangen... Allerdings noch wieder ohne sieve und quote. Aber ich muss jetzt auch mal was Arbeiten
Manmanman... Sowas macht man aber auch nicht in ner Minor-Version, #Dovecot.

Okay I've used up all other options, so now it's #FollowerPower and #FediMagic :

Would someone here be able to help me fix my broken #Yunohost instance? I've been without email for several weeks now

All apps and admin interface work without problems, but #Dovecot fails to start with a cryptic #SSL error. I've tried the forum of course but so far without success.

Happy to share logs and all. Thanks a million!

An update to @sacha 's gnus local imap pipeline config, due to dovecot 2.3 -> 2.4 breaking changes:

1. Note mail_location option split up. Specify all options like this:

(nnimap-shell-program "/usr/libexec/dovecot/imap -o mail_driver=maildir -o mail_path=$HOME/Maildir -o mail_inbox_path=$HOME/Maildir/INBOX -o mailbox_list_layout=fs")

Alternatively, put everything into system config.

2. System config must have these two lines:

dovecot_config_version = 2.4.1
dovecot_storage_version = 2.4.1

3. Official migration guides:

<https://doc.dovecot.org/2.4.1/installation/upgrade/2.3-to-2.4.html>
<https://doc.dovecot.org/2.4.1/installation/upgrade/2.4-to-2.4.x.html>

P.S.

Offtopic. Helpful resource on the upgrade: <https://willem.com/blog/2025-06-04_breaking-changes/>

Sample configs: <https://source.willem.com/dovecot-2.4-sample-config/>

because running a mail server wasn’t fun enough: the Dovecot 2.3 → 2.4 update has tons of breaking config changes

(h/t to https://willem.com/blog/2025-06-04_breaking-changes/ for the exhaustive breakdown of the changes)

That whole #dovecot breaking update (and from what I've seen the unreasonable pro version, at least for small setups) makes me question self-hosting my mail server…
I'm fine with investing time to setup something the first time - but updates (especially not minor) should never be breaking… - neither should they require quiet some time investment imho…
#SelfHosting #mailserver

@stefano would have happily paid a reasonable price for the commercial version of #dovecot, but the pricing is only targeted at large ISPs, so everyone with less than 10k mailboxes isn't interesting at all to them. I asked them a few months back just after the deletions happened in their repo. Didn't even ask about #freebsd support.

For anyone who just upgraded to #dovecot 2.4 (it's now in debian testing), the deliver command now doesn't work unless you specify -d <user> as well as -m <mailbox>

This bit me badly because I use procmail with deliver and it was simply throwing away all inbound email.

#Dovecot Does anyone know how I can use the #zlib plugin to compress my mail archive while transferring from another server? I tried to set it up, but the mail just comes over as-is. The docs suggest that it should convert with #dsync to compressed files. I seem to miss something. #help
