As you can see in the logs, the server replies with zero messages. This happens because you're moving messages. The sequence numbers change when messages are moved around (see the EXPUNGE notifications in the logs). For instance, when moving message 35 to another mailbox, the sequence number is decremented for all messages with a sequence number ≥ 36. You can use UIDs instead of sequence numbers if you want an identifier which doesn't change.
Closing since this isn't a go-imap bug.
