Exchange 2010 - Method to send e-mail when the WAN IP is dynamic

Hello,

I am writing due to the fact that I cannot send e-mail from my Exchange 2010 Server to my Yahoo! address for testing. When trying to do so, I get the following error message:

mta1106.mail.gq1.yahoo.com gave this error:
Mail from xxx.xxx.xxx.xxx not allowed - 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; see http://postmaster.yahoo.com/errors/550-bl21.html [550]

As one can see, because my IP address is residential, I cannot send e-mail to all addresses on the web. I really would like to use this as my primary contact, and thought of using a proxy. Can someone recommend a good proxy, or workaround for this? I am sorry for posting in Exchange 2013, but I couldn't find the 2010 forum. Thank you to all who reply.

Thank you for your reply,

I have set up DynDNS, and I am currently using my own domain name. The problem was I needed to configure a smart SMTP host, or relay server on my send connector. I decided to go with SMTP2GO, as they are cheap, and allow you to send 20 e-mails a day for free. When the money is right, I plan to upgrade.

Thank you for your help.
