Right. After playing more and reading bits of an rfc, it is after all the
"go ahead" violation of the IMAP protocol. So despite my last message,
Lele was absolutely right after all.

Playing with 
openssl s_client -connect mail.btinternet.com:993  -crlf
also seems to show other violations of rfc3501 such as in the correct
wording of some responses.

As I said earlier, I think offlineimap/imaplib2 really ought to report
the violation at the very least.
