I tried that before, that would be great if it worked for
imap, but I've verified that the dotlock file does not get
created in /var/spool/mail/username.lock when I open the
imap connection, at least for reading.  It is created when I
open the popmail connection (but that was already working.)
That's why I'm asking.
