[Dovecot] dovecot-1.2.9: OK No messages copied

[Attila Sipos]

OK, clearly I am not experienced enough in IMAP to argue.  I am sure the imap-protocol people will tell me to get lost!

Thanks for your time.  If you could possibly tell me how to know if an IMAP "UID COPY" is successful, I would appreciate it.
Basically I'm moving a message from one folder to another.  I thought I could issue a COPY command, check for success, then delete the email from the source folder.

Regards
Attila

It might be more useful from your point of view, but it might not be from from someone else's point of view. If you want this changed, see if you can convince other people in imap-protocol list. All of the widely used IMAP servers behave the way Dovecot does.
