[Dovecot] dovecot-1.2.9: OK No messages copied

[Timo Sirainen]

Note how Dovecot sent the client EXPUNGE notification. Prior to that
client knew that the message existed. After that client knows that the
message no longer exists. It was only during the COPY command that
client didn't know that the message had already been expunged.
