Hi there,

I have a Postfix/Dovecot server which today I upgraded from Alpine Linux 3.21 to 3.22. In the process, Dovecot updated from 2.3.21 to 2.4.1, and I updated my Dovecot config accordingly. At least doveconf -n runs without any error, and I'm able to start and run Dovecot.

Fatal: Couldn't load required plugin /usr/lib/dovecot/lib90_sieve_plugin.so: dlopen() failed: Error relocating /usr/lib/dovecot/lib90_sieve_plugin.so: mail_deliver_get_return_address: symbol not found

Hi,

I never used Alpine. But from your doveconf:

2.4.1-4 (7d8c0e5759): /etc/dovecot/dovecot.conf

Pigeonhole version 2.4.0 (1b2d5bb9)

They should be both the same version. So try upgrading the dovecot- pigeonhole-plugin package.
