Hi, I'm using the Dovecot Prebuilt Binary: deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.2 main It seems, that the Prebuilt Binary provided at least once the 2.3 version, because doveconf -n shows: # 2.3.devel (5e7036c): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (ef25ce6) # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.10 Now Prebuilt Binary provides the 2.2 version again, but I get some error messages on updates: Preparing to replace dovecot-imapd 2:2.2.23-1~auto+14 (using .../dovecot-imapd_2%3a2.2.23-1~auto+16_amd64.deb) ... doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_login_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) and: Preparing to replace dovecot-core 2:2.2.23-1~auto+14 (using .../dovecot-core_2%3a2.2.23-1~auto+16_amd64.deb) ... doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_login_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) doveconf: Error: Couldn't load plugin /usr/lib/dovecot/modules/settings/libmanagesieve_settings.so: Module is for different ABI version 2.2.ABIv20(2.2.devel) (we have 2.3.ABIv0(2.3.devel)) After the update doveconf -n shows: # 2.2.devel (8828071): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.devel (ef25ce6) # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.10 How can I go back to ABI version 2.2?
