Inbox empty and no folders showing after upgrade from Fedora42 to 43.

[Durwin]

I use fetchmail and procmail to retrieve email from my ISP.  It is delivered to the users /var/spool/mail/ files.  This still works.  Using Mutt I can view my new mail.  After the upgrade to Fedora 43 all I see in Roundcube is an empty Inbox and Sent.  None of my Folders show.  There are no errors in error logs.

roundcubemail-1.6.11-2.fc43.noarch
php-8.4.14-1.fc43.x86_64

Here is my config.inc.php

<?php
/* Local configuration for Roundcube Webmail */
$config['db_dsnw'] = 'mysql://USERNAME:PASSWORD@localhost/roundcube';;
$config['smtp_log'] = false;
$config['imap_host'] = 'MYDOMAIN:143';
$config['support_url'] = '';
$config['auto_create_user'] = false;
$config['des_key'] = 'SOMEKEY';
$config['plugins'] = [];
$config['prefer_html'] = false;

Thank you for your time.

This would most likely be an issue with your IMAP server. To verify you could enable imap_debug in the Roundcube config and check the <RC root>/logs/imap.log to verify what the IMAP server is returning.

Thank you for your reply.

This is from the imap log.  I do not see anything out of ordinary.  I noticed it references Dovecot.  Dovecot is a fresh install.  I have not done any configuration.  It's config is after imap log.

I can see from the IMAP log that Roundcube is working correctly, its asking for messages in the inbox "C: A0003 STATUS INBOX (MESSAGES UNSEEN)" and then Dovecot says there are no messages "S: * STATUS INBOX (MESSAGES 0 UNSEEN 0)"

This is most likely a configuration or maybe a permissions issue with Dovecot. You'd need to dig further into the Dovecot logs and configs to confirm.

Hi SKaero
After enabling logging in Dovecot I can see the path to the ~/mail/ folder is correct.  I can see a 'permission denied'.  Is it saying no permission to access ~/mail/ folder?  This is what I have.  I seams it is saying these rights are not correct.  If that is true what should they be?  Obviously things have changed (not my machine though).  All worked before upgrade to Fedora 43

My fix is putting these lines in dovecot.conf

mail_home = /home/%{user}
mail_driver = mbox ← changed this from maildir
mail_path = ~/mail
mail_inbox_path = /var/mail/%{user} ← added this

And adding the 'user' to the 'mail' group.
