Hello, lately I receive spam which looks like coming from my domain,
sometimes it is spoofed like coming from accounts that don't exist, and
sometimes from the ones that really do (and actually, From header is forged
like the email is coming from several accounts...). I'm surprised that it
gets through because I thought that Exim does reverse DNS lookup and
confirms that the IP address of the sender's server resolves to the domain
of the user that it is supposed to be coming from, but it seems not? What
would be the most elegant and technically correct way to get rid of the
problem?
