I can think of at least four ways they could have your server's name:
1: DNS records.
2: There is a web server out there.
3: The web archives of this list.
4: They could have a port scanner of wide swaths of IPs that just tries
port 25 on all of them.

They're clever monkeys, our spammers are.  There is no security through
obscurity, unfortunately.
