This is strange... IIRC, some years ago someone else had a problem with
Exchange, and the problem seemed to be that the IMAP SEARCH
functionality was disabled by some option in the server.  But in your
case only the SEARCH SUBJECT seems to fail...

If you do contain_header('Subject: ***SPAM***') does it work?  It looks
like it would work in your case...

Also, you could do match_subject(), but have in mind (you probably know
it already) that while this would lighten the burden of searching from
the server, you would have to waste some bandwidth in order to fetch the
Subject header from all messages (of course this way you can also do
regular expression matching)...

Yes...
