Wrote my smtp server 5 years ago. Still running.

BTW, did you know the smtp protocol works without DNS?

You just need to puth the ipv4 between brackets @[xxx.xxx.xxx.xxx] and for ipv6 @[ipv6:...].

spam? simplicity and freedom has a price (personnaly, I have have very, very little spam since I am self-hosted), and don't think corpos won't try to force you to use their servers one way or another... Whose coding the virus? It is sane to presume it is the seller of anti-virus software...

I did but assume no-one uses that as it's not practical because most IP addresses serve more than one domain? Or does SMTP handle that, like some extra "really-to:" header to encode the user@domain if you use IPvX for delivery?
