Sendmail does _not_ do this by default; you have to specifically allow it by adding entries to your M4 file from which you build your sendmail.cf. If I had to guess, I'd guess that you enabled the domain via a sendmail.cw file, rather than a virtusertable, or by setting yourself up as a promiscuous relay. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
