Dear Noah. 1) Is this server the primary MX for this domain (has the lowest MX = record in the dns) ? If so, you need to look at something called mailertables. = That allows you to retrieve mail for a domain and then forward it to another = SMTP (or UUCP for that matter) host. For this to work you have to add the = line "FEATURE(mailertable, 'hash -o /etc/mail/mailertable')" to your = freebsd.mc file and do "make cf". The format of this file should be customerdomain.com smtp:[mailserver.customerdomain.com] Note, this file is not plan-text and has to be compiled with make maps. = More info can be found at Sendmail webpage; http://www.sendmail.org/m4/features.html 2) If not; hmm. Sendmail should figure out where the final destination should be. How are the MX records for this domain? Hope this helps, Bj=F6rn Swift -----Original Message----- From: Noah Davidson [mailto:Noah@oopz.com]=20 Sent: 30. jan=FAar 2002 19:52 To: Bj=F6rn Patrick Swift Subject: RE: Secondary MX I did this, but the mail bounces with the error MX points back to me error. How can I specify the domains that can relay, and also work as = a secondary MX to queue the mail?

First, edit your sendmail.cf file and make sure it includes a line like this one: FR-o /etc/mail/relay-domains The edit (or create if necessary) your /etc/mail/relay-domains. The format for this file is basically "domain per line" so a line including "customerdomain.com" should do the trick.

We have some customers that have their own mail servers. We want our secondary mail server to = queue mail until their server comes up on line then deliver it. I know how = to set the priority in the MX records in DNS, but sendmail does not seem = to queue the mail. I have added the domain in which I want to queue the mail for in the relay-domains. I thought I read that somewhere. = Should this be done in the access using a line like: To:domain.com RELAY or how should this be done?
