[Mimedefang] spamassassin MISSING_HEADERS Missing To: header

[ben williams]

Hi,
I'm using mimedefang 2.67 from Fedora EPEL. When mimedefang processes a 
message using spam_assassin_check() the above spamassassin rule is never 
triggered. But if I run spamassassin on the command line (without 
mimedefang) and give it a message with no To: header, the rule is triggered.
Has anyone encountered this problem?

Thanks
Ben
