Hey,
I have two mailservers running OpenBSD 6.9, and I use bidirectional
syncing of my maildirs through doveadm, part of dovecot. After the
upgrade, I noticed that the sync process was failing.
Here's a sample run:
kefka|~|02:57:05|0$ doas doveadm sync -u w...@worrbase.com
remote:sabin.worrbase.com
doveadm(VERSION dsync 3 5): Error: User doesn't exist
dsync-local(worr)<FNQIMvI9omB4VwEADTvxNg>: Error: read(sabin.worrbase.com)
failed: EOF (version not received)
dsync-local(worr)<FNQIMvI9omB4VwEADTvxNg>: Error: Remote command returned error
67: /usr/bin/ssh -i /root/.ssh/id_ed25519.dsync sabin.worrbase.com
/usr/local/bin/dsync-in-wrapper.sh
kefka|~|02:57:08|75$ cat /usr/local/bin/dsync-in-wrapper.sh
#!/bin/ksh
read username
/usr/local/bin/doveadm dsync-server -u "$username"
I ktraced the process, and noticed that in the communication with the
remote mail server, that a bunch of doveadm plugins fail to load. It's
worth noting that these are plugins that are dlopen(3)ed in response to
certain commands sent over the wire, so they don't show up in ldd(1) output.

I checked on both machines, and these symbols are all undefined in the
associated libraries. I do notice though, that these symbols seem to be
present in similar dovecot, non-doveadm plugins:
kefka|~|03:04:56|130$ nm -A
/usr/local/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so | grep
acl_user_module
/usr/local/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so: U
acl_user_module
kefka|~|03:05:14|0$ nm -A /usr/local/lib/dovecot/lib01_acl_plugin.so | grep
acl_user_module
/usr/local/lib/dovecot/lib01_acl_plugin.so:0001b008 D acl_user_module
However, the doveadm plugins don't link against them?
kefka|~|03:04:24|1$ ldd
/usr/local/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so
/usr/local/lib/dovecot/doveadm/lib10_doveadm_acl_plugin.so:

Is anyone else seeing issues like this? Is there perhaps a
misconfiguration on my end?
Both are running dovecot-2.3.14p0v0 from packages with
dovecot-pigeonhole-0.5.14v1.
pkg_check -F showed nothing unusual that was dovecot-related in /usr/local
