IMAP Spam Begone (isbg)

Hi.

I am getting the same error with multiple accounts (on the same server with mailenable)

at first it is ok...

./isbg.py --verbose --imaphost mail.xyz.com --imapuser someone@xyz.com --flag --savepw
Trackfile is /root/.isbg-tracke548338bae5b069370985d0a759af9fd
SpamFlags are (\Flagged)

imaplib.abort: command: UID => unexpected response: 'Received: from Vega (29-123-43-38xxxxxxxxxxxxxxxxxx)'

This was with version 0.97, the same with 0.99. With different accounts, the same problem "imaplib.abort: command: UID => unexpected response:"

Any issues known like that?

Thank you for your answer, best regards, Nejc.
