What hostname Sendmail needs to contact, and what MX records are associated with it. b) Routing. What IP address DNS said should receive mail, and through which route this can be contacted. So you don't have Sendmail problems. Something in DNS setup or routing table is going funny. -giorgos To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
