Good Day, I'm trying to bring up a new machine that serves several purposes and have run into a potentially Very Big Problem.
The machine has two physical interfaces, one LAN-facing and one Internet-facing. So, naturally, I have something like: Let's say 10.1.1.0 is the Internet-facing network and 192.168.1.0 is inside. inet_interfaces = 10.1.1.4, 192.168.1.1 The machine has its "real" interface and additional virtual (or alias) interfaces on the outside: 10.1.1.2 hostname.example.com 10.1.1.3 ns1.example.com # alias/virtual 10.1.1.4 mx1.example.com # alias/virtual and so-on. The problem is: On outgoing connections to The World, via the 10.1.1... interface, SMTP clients, instead of binding to 10.1.1.4, are binding to 10.1.1.2, rather than 10.1.1.4. I can't use smtp_bind_address, because the server also delivers email to an internal server on the 192.168.1.0 network. So, do I either have to swap the addresses of "hostname" and "mx1" (which would be kind of lame, IMO) or do-away with "mx1" entirely, and let "hostname" be the MX? ISTM Postfix' SMTP clients should chose from the interfaces listed in inet_interfaces or smtp_bind_address should be smtp_bind_addresses, and it should chose from them. Thanks, Jim -- Note: My mail server employs *very* aggressive anti-spam filtering.
