Hi Aki!

The config is in the attachment.

The output from gdb is this:

And i have a complex setup for virtual mailboxes...

For Synoptic/AKTUELL it is:

# cat /var/mail/virtual/AKTUELL/dovecot-virtual
!Real/halbjahr
  all

And for Real/halbjahr it is:

# cat /var/mail/real/halbjahr/dovecot-virtual
!Real/Alle
  all younger 15768000

And for Real/Alle it is:

# cat /var/mail/real/Alle/dovecot-virtual
