[imapfilter-devel] No match with contain_subject on Exchange server

[Bernd Kuemmerlen]

Hello,

we recently migrated from a postfix system to an Exchange server (don't 
ask).

I have been running a large set of imapfilter rules on the postfix 
server without problems. Now, on the Exchange server, all queries using 
contain_subject() do not seem to return any results

The configuration

results = account.INBOX:contain_subject('***SPAM***')

returns nothing, even though there definitely is a message where the 
subject matches.

Matches with contain_from() seem to work.

Any idea what might be the problem here?
