Virtual Static IP Address

I have Verizon DSL and would like to host an e-mail server. Now, Verizon DSL only provides dynamic ip address. I heard of a website, www.dynip.com, that helps on you on setting up virtual static ip address for you DSL service. They charge about $36/year for this and you get a domain name (yourpc.dynip.com). Does anybody know anything about this, or another way around this? Let me know.

tks!
