Hello, I'm wondering if it's possible to configure a smtpd process in master.cf to send messages to the outside on a secondary network interface. It seems to be possible to make a smtpd process listen on a given interface (IP address) by specifying the IP address on the front of the configuration line like so (where "bbb.bbb.bbb.bbb" is an IP address affixed to a secondary network interface):
bbb.bbb.bbb.bbb:smtps inet n - n - - smtpd But when sending mail, it still seems to go out on the machine's primary network interface. Help much appreciated.
