[offlineimap] Unable to sync IMAP - looping with "reader poll => []" (#207)

I'm trying to configure IMAP with Polish hosting provider home.pl and have problems with syncing any message. They use custom IMAP server. I tried telnet and mutt to verify if IMAP works and have no problem with login and listing directories. Despite that offlineimap hangs on `reader poll => []` and can't proceed further.

Log with `-d all`:
