Nobody is breaking any standards... It is just that this server
implements the (obsolete) RFC1730 IMAP4 protocol, while imapfilter works
with RFC3501/RFC2060 IMAP4rev1 protocol servers.

I don't believe that if this server reports IMAP4 will work with
imapfilter.  For example imapfilter uses the IMAP4rev1 STATUS command
(which IMAP4 lacks).

No, this isn't a good idea.  Imapfilter works with IMAP4rev1 compliant
servers.  I don't see what one is aiming to accomplish by sending
IMAP4rev1 commands, to something other than an IMAP4rev1 server.

It would be a good thing to try and make imapfilter work with IMAP4
(besides IMAP4rev1) servers, since there aren't so many differences
between the two protocols, and I plan to look into it some time.
