Due to my old ldap server (with samba 2.X) dying I wanted to decouple the emails from the rest of the accounts since only 3 users actually use the email anyway the whole setup with LDAP was complete overkill..
So while tracking down problems with performance with (webmail - ) clients I found out, that the problem is - at least partly - related to the sheer amount of IMAP folders (dbmail_mailboxes) a user had ( > 3500 !).
