Question being: I want to set up host abc.edu as MX forwarder for domain xyz.org, whereas host def.edu (which takes to abc.edu via smtp) takes care of all xyz.org mails, could someone point me to the standard way to have it set up, with sendmail.cf (or elsewhere)? Eg., how does major MX gateways running SMTP do that, TECHNICALLY? In short and again, host abc.edu will receive all mails for xyz.org and forward it to def.edu for final delivery. NOTE: root@xyz.org should NOT be forwarded to root@abc.edu (ie, xyz.org is not to be set up as an alias of abc.edu; and that the RFC822 From: header should not be modified) You can assumption: 1. the MX record for xyz.org is already in the DNS system & readily resolvable. 2. abc.edu and def.edu can talk to each other via smtp Thanks in advance, /aaron. aaron@ux.acs.umn.edu
