Hollingsworth) writes: For incoming mail, we can set up mail exchange hosts using bind's MX feature. We'd like to have the same 'centralized' control over outgoing mail where mail to Internet hosts would be routed through one or two or our hosts before being sent out to the Internet. I know this can be accomplished using sendmail.cf options; however, this would require changing a lot of sendmail.cfs. Does anyone know of a an easier method to accomplish this? How about setting everybody up with mailhost.jhuapl.edu? You can then MX mailhost to whatever you would like. I know that this would involve changing the sendmail.cf. But, then again, this would mean you would only need one sendmail.cf for other than your MX hosts. mailhost in a whatever.his.address.is in mx 0 primary.mx.host. etc.... One behavior that might come up is that if the primary mx host is down, the available alternates will immediately forward to the internet. This seems to go against what the MX record is for, but then again, that is the behaviour that I think you are looking for. I haven't given this much thought though.
