Well, it's a matter of philosophy, I guess. I can't see sendmail.org accepting a patch for this. Look at it this way: Sendmail has every reason to assume that if an SMTP client has a broken implementation of the state machine on one message attempt, it probably will break on every attempt, so why tempfail? > This would not encourage the developers of broken servers to fix them > or administrators to migrate.

True; if bandwidth is a scarce resource, this could be an issue. It isn't for us, and I suspect it isn't for most people -- I doubt e-mail uses the majority of bandwidth at most organizations. Web browsing, P2P and FTP probably swamp e-mail.
