Fails to connect to an email server running dovecot 2.3.21 and postfix 3.9.0 #9612

Closed berolinux closed 1 day ago

berolinux commented 2 months ago

Steps to reproduce

  1. Try to configure a mail account

Expected behavior

Mail account is configured, can proceed to my mail

Actual behavior

"SMTP connection failed" -- but the access data is correct and other mail applications (KMail, SOGo, K9 Mail) connect to the same server fine. The mail server is running on the same machine as nextcloud, definitely no firewall issue or stuff like that. SSL certificates look fine (and are accepted by the other mail applications).

Mail app version

3.6.0

Mailserver or service

local mail server setup using dovecot 2.3.21 and postfix 3.9.0

Operating system

OpenMandriva Cooker on aarch64

PHP engine version

Other

Web server

Nginx

Database

PostgreSQL

When the error happens, occ log says

The mail server log shows the connection attempt, but no indication of anything going wrong.

Hi @berolinux,

Look like its failing while trying to retrieve the ACL for the 'Archive' folder. "Horde_Imap_Client_Base->getMyACLRights("Archive")"

Is there anything special with this folder?

Can you enable the Nextcloud debug mode ('debug' => true,) in the config and try connecting to the mailbox again?

Then post the output of the horde_imap.log
