The 9grid technique might work among cooperating plan 9 sites if we can figure out how to make the authentication require less effort by the site administrators. It's really easy when the authentication is set up; to deliver mail to user@machine, import -bp machine /mail/box mail user It just works. No SMTP involved, just local delivery. Thanks, Dave. For those who can't talk 9P, I'm trying the experiment of asking friends to also listen on an alternate port for SMTP; I'm already doing so. Once we get a few sites doing it, a few lines in rewrite can select the alternate port for those sites. I'm not publishing the port number in public, to discourage spamming. Mail arriving on the alternate port gets less scrutiny and eventually mail to port 25 might get tossed into a `probably crap' mailbox. Oh, there's a sick idea: revive UUCP over TCP.
