Hello everyone, I have a Dovecot 2.3 installation on a Debian 12 Linux system that is being upgraded to Dovecot 2.4. The server hosts many domains with numerous email accounts. Users had created folder structures containing many received and sent emails, following the Maildir standard as "dot-prefixed folders."
When switching to Dovecot 2.4, all these emails and folders are no longer visible. This is what it looks like on the old system: root@mx1 /var/vmail/example.com/systemmails # ll -a insgesamt 256 drwx------ 14 vmail vmail 4096 3. Nov 09:15 . drwx------ 15 vmail vmail 4096 6.

Dovecot 2.4 works quite differently in this regard. What solution is there for migrating both the namespace and the existing emails to Dovecot 2.4? Thank you for your suggestions ByteMe _______________________________________________ dovecot mailing list -- [email protected] To unsubscribe send an email to [email protected]
