Re: bind and outgoing mail relay
Date: Wed, 29 Oct 2008 08:32:21 -0700 From: Justin T Pryzby [EMAIL PROTECTED] To: bind-users@isc.org Subject: bind and outgoing mail relay I wonder if there's any way of using our local recursive server for forcing all locally-originating mail to go through a given mail hub. I suspect not? Not via DNS. The setup is with the sendmail.cf (or what ever config file you use).

If you're using Postfix, see following description taken from Postfix's main.cf: # The relayhost parameter specifies the default host to send mail to # when no entry is matched in the optional transport(5) table.

If all of your mail clients use MX records for routing mail, and if you have an internal-root architecture with no direct Internet resolvability (i.e. all Internet access is through application-level gateways), then you can do this with wildcards in your internal root zone. - Kevin
