Question : Exchange Server on a Dynamic IP

Hello,
I am using Dynamic DNS.
I pointed my MX record to my Dynamic DNS URL.

Am I susceptible to being Blacklisted if my Exchange Server has a dynamic ip associated with it?

If so, what is the best way around getting blacklisted, but still maintaining a dynamic ip?   I have heard of a 'Smart Host' before; should I use something like that?
Should I talk to AT&T about anything?

I know I cannot have AT&T create a Reverse PTR record, because my ip is dynamic and not static.

Thank you.
