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, Björn Swift -----Original Message----- From: Noah Davidson [mailto:Noah@oopz.com] Sent: 30. janúar 2002 19:52 To: Björn 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?
