Hi,
I would like to allow mail from a known e-mail address say
[email protected] <mailto:[email protected]> with an attachment say X to a
user in my domain say [email protected] <mailto:[email protected]> ,but
at the same time reject another e-mail from an e-mail address different
from [email protected] <mailto:[email protected]> to [email protected]
<mailto:[email protected]> 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.
