Hi,
I would like to allow mail from a known e-mail address say
a...@example.com <mailto:a...@example.com> with an attachment say X to a
user in my domain say u...@kenkob.co.ke <mailto:u...@kenkob.co.ke> ,but
at the same time reject another e-mail from an e-mail address different
from a...@example.com <mailto:a...@example.com> to u...@kenkob.co.ke
<mailto:u...@kenkob.co.ke> with attachment X.
How do I implement this using header-checks?
You can't. Postfix header_checks operate one line at a time,
so it's not possible to combine {sender + recipient +
attachment} checks.

You may be able to do this with a content_filter or milter,
but I can't recommend a specific one.
