[Dovecot] Deleting messages with Mac Mail via IMAP

[Urban Loesch]

Hi,

if I remember correctly, there is no option in the IMAP protocol to move 
a message per se.

Moving a message to trash or elswere will copy the message first and 
then mark the message as deleted from original folder. If you would like 
to delete it immediately after storing in the odther folder, there must 
be some flag (expunge) to set in your mail client.

As I just said, I'm not shure if I rember correctly.

Regards
Urban
