My ISP is blocking port 25 what can I do?

Currently, I have a register domain with godadddy.com and looking to setup up a 2007 exchange server. After extensive research research, I’m finding out that my ISP is blocking port 25. This explains to me why I can only send email internally and why I’m not able to send or receive to an external address. I realize I need to change my send a listing ports on my server.. But how do get my email to come in through a different port through using godaddy. Is there any type of mail hop service offered or port redirection?

It sounds like you may simply need to be adding a SSL Certificate to force mail through secure port as oppose to the 25.
With Exchange 2007 you would need a UCC Certificate. To see more regarding this please visit the following:
