Changes don't seem to be getting posted upstream

Hi,

When I delete a message locally using mutt, then purge it, it doesn't
seem to get deleted on the remote server?

I've included the output of offlineimap -d imap -u ttyui with some of
the juicy stuff redacted:

In my config I've got:
readonly = False

Any help, pointers or requests for more info greatly appreciated!

Thanks,
Edward
