Hi, I currently use multiple Postfix instances to send email from my server from different IP addresses. Each Postfix instance has its own master.cf file in its own configuration directory, and I use the "-C" parameter of the sendmail command to specify which one to use.
I was wondering whether there is a better way to do it, preferably with a single Postfix instance and single configuration directory? I see that multiple IP addresses can be specified in master.cf, but I can't see a way to tell the sendmail command which one to use. I've looked at smtp_bind_address in main.cf, but I'm not convinced that's the right thing to use. Should I just stick with multiple Postfix instances? Postfix version is 2.7.1 on Debian Squeeze. Thanks, Andy
