Panix.com allows unlimited email addresses in the format: whatever@myname.users.panix.com where "whatever" is anything you like, and "myname" is your email name. (You also have the address "myname@panix.com".) I've been challenged on this only once. And I've been able to tell a company that its email list has been compromised.
