[Mimedefang] filter on header From:

[Marcus Schopen]

Hei,

I have a text base list of email addresses (one email per line). Where
would I best filter on header "From: " (not envelope from) in
mimedefang-filter and add an additional mail header in case of a hit? At
the moment I use spamassassin rules to tag such mails in filter_end, but
spamassassin catches only mails if their "./INPUTMSG" smaller than the
global given message size, which I don't want to increase.

Ciao!
Marcus
