[Dovecot] Transition from Courier-IMAP

[Arno van Amersfoort]

Thanks for the info concerning the namespaces.

And yes: my users (including myself) use the EXPUNGE-to-TRASH option and 
as I said before we can't update all computers running Thunderbird here 
to enable copy-to-trash. And "mark-as-deleted" doesn't work in 
combination with "copy-deleted-to-trash" the options are exclusive to 
each other....
