Hello,

Is there a way to block all incoming mails by the content of return-path. I've too many spams coming right now and all of them has the return-path like "<>"

I think the return-path must not be empty by the way. Would it be loss if I block all incoming mails with the return paths empty.

Thanks all.
 
You'd eventually end up in the rfc-ignorant list. I don't know if anyone blocks based on that list.

The reason the RFCs require that you accept all emails coming from the return path of <> is that Mailer Daemons use that to send delay and undeliverable messages back to your server.

Yes, through custom configuration of exim.conf. Custom setups using exim.conf are beyond the scope of this forum.
