View Full Version : blocking by return path

06-11-2009, 04:27 AM

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.

Is there a way to block outgoing mails which has .ru extension.

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