Even getting a static IP address will not help if they are on DSL.
Most ISPs will report all of their DSL connections as dynamic. Most "static" IP addresses are just reservations in a dynamic range and you will be surrounded by dynamic IPs.
Plus if you are on DSL you will be unable to get reverse DNS configured correctly, so other people will block you on that.
The best solution for all DSL users is to use an SMTP Connector to route email via your ISP.

Please let me know how to fix this issue and/or get around it.
