He has a machine "en26.groggy.anc.acsalaska.net"; this is the mail server. It's behind a NAT box "groggy.anc.acsalaska.net" with IP address "208.151.119.232". Forward and reverse address mappings are correct for the NAT box. Because he is not masqurading the domain, on outbound SMTP connections, he's saying: "ehlo en26.groggy.anc.acsalaska.net" and: "mail from: <groggy@en26.groggy.anc.acsalaska.net>" instead of the correct thing, which is: "ehlo groggy.anc.acsalaska.net" and: "mail from: <groggy@groggy.anc.acsalaska.net>" Since "ehlo en26.groggy.anc.acsalaska.net" is not a resolvable name, his mail is getting rejected. Pretty simple. I'll bet his biggest problem is that he's using "qmail" or "postfix" or something other than "sendmail" (the latter is easily configured for proper masquerading of domains). Supporting inbound email through the NAT box to the interior SMTP server... that's a whole additional problem. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
