Which RFC ???
In fact, RFC 2822 which obsoletes RFC 822 doesn't even mention relays.
Of course. It also doesn't mention space ships. It's just about something else. It has not anything to do with "email relaying". The right one is RFC 2821. See the quote of "Relaying" part from my previous post.
Is there any RFC that specifies that open relays are a bad idea?
Do not expect that there is an RFC for every bad idea around ...
I can't find one.
I can. RFC 2505 Anti-Spam Recommendations February 1999 2.1. Restricting unauthorized Mail Relay usage [..] Therefore, the MTA MUST be able to control/refuse such Relay usage. [..] ... MTA MUST be able to authorize Mail Relay usage based on a combination of: o "RCPT To:" address (domain). o SMTP_Caller FQDN hostname. o SMTP_Caller IP address.
