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.
