Resolved Dovecot problem after upgrade

decanet

Basic Pleskian
Hi,

After an auto upgrade, IMAP and POP are broken on Dovecot.

The upgrade was for:

Code: 
127.0.0.1 admin [2016-11-28 13:56:01] 'Plesk component upgrade' ('COMP_SERVICE_NODE': '1' => '1', 'Plesk component name': 'dovecot' => 'dovecot')
127.0.0.1 admin [2016-11-28 13:56:02] 'Plesk component upgrade' ('COMP_SERVICE_NODE': '1' => '1', 'Plesk component name': 'dovecot-pigeonhole' => 'dovecot-pigeonhole')
127.0.0.1 admin [2016-11-28 13:56:02] 'Plesk component upgrade' ('COMP_SERVICE_NODE': '1' => '1', 'Plesk component name': 'roundcube' => 'roundcube')

Now, on each IMAP/POP connection, I can see in logs:

Code: 
Nov 28 14:25:06 xxxxx dovecot: auth: Fatal: Couldn't load required plugin /usr/libexec/dovecot/modules/auth/libauthdb_plesk.so: Module is for different ABI version 2.2.ABIv17(2.2.18) (we have 2.2.ABIv26(2.2.26.0))
Nov 28 14:25:06 xxxxx dovecot: master: Error: service(auth): command startup failed, throttling for 4 secs

I've the same problem on 20 others Plesk servers (CentOS 6 and CentOS 7 servers).
After 2-3 tests, the solution was to run manually :
Code: 
# /usr/local/psa/admin/bin/autoinstaller update plesk
and apply microupdates.

Hope this will help people who have the same problem.
 
After the manual update, i rebooted the machine and can not send emails (I'm using postfix).

Checked the service:

service postfix status
master est? parado

So,
service postfix start
Iniciando postfix: [ OK ]

But there is not an entry to start postfix in boot

chkconfig --list |grep -i post
postgresql 0:desactivado 1:desactivado 2:desactivado 3:desactivado 4:desactivado 5:desactivado 6:desactivado
udev-post 0:desactivado 1:activo 2:activo 3:activo 4:activo 5:activo 6:desactivado

Don't wan't to add it manually, but note this if after reboot it doesn't work
 
Hi,
Could you check which options are selected in Tools & Settings > Update and Upgrade Settings?

The issue with postfix looks not linked with update, what is your OS?

All our servers have same update and upgrade settings than jterry's screenshot.

jterry, you seems to have a second problem, not linked to the first one. Have you tried a
Code: 
# plesk repair mail
?

Can you check the /var/log/maillog to check what's the problem if the repair didn't fix it?
Click to expand...

Sure, but the problem is not mail server configuration related, the services/runlevels line for postfix gone after the update

Code: 
# plesk repair mail

Repairing the mail server configuration
 
  Reconfigure all domains and mailboxes? [Y/n]
    Reconfiguring all domains and mailboxes ......................... [OK]

Error messages: 0; Warnings: 0; Errors resolved: 0

Mail (SMTP) is working after run service postfix start

I'm pretty sure i can solve this with

Code: 
# chkconfig --add postfix
# chkconfig --level 2345 postfix on

But don't want to touch anything waiting if an update resolves it (to avoid conflicts)
 
Oh OK, I have understood mail sending was broken despite of Postfix was running.
I haven't postfix in my "chkconfig --list". Postfix is started from psa service I guess:

Code: 
# service psa start

I considered that before but not tested about that, i've done now...

Note this:

# reboot

PSA STARTS postfix if invoked manually, but not during boot. Perhaphs this give some light about this problem.

I'm going to try a repair

Thanks
 
I did

/usr/local/psa/bootstrapper/pp17.0.17-bootstrapper/bootstrapper.sh repair

But didn't solve this
 
Issue with broken auth in dovecot is confirmed for case when dovecot is updating automatically by yum/apt or when "Automatically install system package updates" checkbox is selected or when dovecot updated by "System Updates" manually.
It's actual only for update packages without Plesk Onyx update #8. Workaround: as decanet mentioned - update Plesk itself.
The issue internal ID is PPP-27009.
