Aihe: [EXIM] Silly Question
Hi! Please don't mind my stupid question:

We run a small ISP and have exim running on 2 machines: one primary and
one relaying to the 1st. We have our MX records on our dns set to 10
for the primary and 20 for the relay.

On busy days, we process ~ 6000 emails on the primary and ~500 on the
secondary. On slow days, we process ~ 2000 on the primary and none on
the secondary.

I have exim set to allow up to 50 concurrent connections. During a time
when my relay machine was receiving mail, I did a netstat on the primary
and saw only 10 connections.

My question is why/how does an outside sender decide to go to my relay
machine, when my main machine is not refusing connections?

Thank you!

Ken.
