why that complex? just point them to a website
webtraffic goes other ways via proxy server then pop3
so just get that fixed !!! Every good proxy solution can work in ways of exposing the real user IP to the internet. Just get that configured!
that's not the point, i understand the difference of *what* goes through a proxy - but frankly *if* it goes through a proxy somebody just knows the public IP and it has to be whitelisted *before* the enduser comes in touch
abuse POP3 and error messages to find your connecting IP is just nonsense, especially in context of imit users to IP's - before WL them they can't connect (otherwise your design is broken)
