MoveMessages not delete message only copy message in destination folder

[edika99]

I'm trying to move mesages from default INBOX folder to specifc folder, but the command copy only the messages in the destination folder but without deleting from the INBOX.
Debugging the DeleteMassages method, the response string passed to SendCommandGetResponse is 'xm010 OK STORE completed.'
The methods ends without throwing exception but al messages are still in the INBOX and a copy has been moved in the requested folder.
