Subject: [exim] detect messages which have a from which don't match RCVD from

Hi,

I would like to Add a custom header to messages which have a From: which includes a specific domain name, lets say domain.com

But have a RCVD From which does not contain that same domain name.

This is basically to detect spoofing,

How can I do this in the exim config file?

Kind Regards,

Jonathan Gilpin
