How do *you* identify the server? You haven't told us. If you don't know
its IP address, you cannot make a connection to it. So, how is a host
(or even a human) that wants to connect to it supposed to find out its
current IP address?
Suggestion: when the "server" connects and acquires an IP address, it
sends its IP address to the client. A couple of relatively simple Perl
scripts could manage this. The client sticks it in a file that Exim can
read.
