Hi, Postfix is running on the public IPs A and B and the private IPs C, D and E.
IP A and B have correct DNS A and PTR records (A: www.mydomain.tld and B: vpn.mydomain.tld). The hostname of the machine is www.mydomain.tld. Currently Postfix-SMTPD answers all connections from clients with it's hostname in the ESMTP header (www.mydomain.tld). How can I configure Postfix to use vpn.mydomain.tld on IP B? Is there an option for transports in master.cf? Thanx for any hint Renne
