Well the clasical answer is 'use a ruleset to identify the networks
from where your customers send mail'.

Since I can't do this, 'cause I don't know where my users are, I use 2
different instances of the MTA listening on different IPs (even if in
the same network interface)... one of them only for incoming mails
(the IP you put in your customers' MX records) and the other for my
customers to send mail (I usually call this IP
smtp.mycustomerdomain.com)... what's more, in this later instance, I
make SMTP AUTH mandatory.
