/**
Compound operation class, performs necessary sequence of commands to delete
a message from a remote mailbox. This may involve SELECTing the appropriate
mailbox prior to issuing the STORE command to mark the message as \deleted.
Note that this sequence of events calls EXPUNGE - the message is deleted
immediately and, once completed, cannot be undeleted.

Stop For Migrate Policy:
	If messages are from multiple folders, the current folder shall be
	completed and then the migration shall be allowed to occur. Remaining
	messages shall be be deleted after the migration has completed.
