Betreff: [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,
