But the server mail.foo.com does not accept mail for arbitrary domains, it accepts mail for foo.com and those domains it controls. | But who says I want to receive such mail anyway? If all the addresses I | use have "@domain.com", then I can expect that no one will send mail | addressed to blah.domain.com, so I have no need to bother with extra MX | records. Because that is not how the real world works, except in dotcomville where the namespace is flat. Case in point, I have a spam trap mailbox on peorth's primary MX that does not exist on her secondary MX. If you try to send mail to ratspahn@gweep.net, it will bounce, but mail to ratspahn@rei.nerv.gweep.net will be delivered. | Gee, thanks for explaining. | I see nothing in 2822 to suggest that Sender should indicate the host | where a message originated. If you do, please point it out. It doesn't, because a message's sender has absolutely nothing to do with where the message originated. | The string "prj@multivac" is generated by the grammar for "mailbox". It is not an RFC 2822 mailbox. It may be a local mailbox to you, but we are not talking about local mail, we are talking about Internet mail. | If the requirement for a FQDN is somewhere else, I missed it. You missed it. From RFC 2822 section 3.4.1: "In the domain-literal form, the domain is interpreted as the literal Internet address of the particular host." A "literal Internet address" of a host is its local host name, a dot, and the local domain name. A mailbox is type addr-spec. addr-spec is `local-part "@" domain'. domain is `dot-atom / domain-literal / obs-domain'. Colloquially, a mailbox is local-part@fqdn (less the root dot). -- Rat \ Happy Fun Ball may stick to certain types Minion of Nathan - Nathan says Hi! \ of skin. PGP Key: at a key server near you! \
