Sounds to me that you need different ISP.

By the way it is not very difficult to configure sendmail to use port which is
different than 25 it that is the mail server that you are using. I personally do not run my own mail server but I would be surprised it Postfix, Exim or Qmail do not have the option of using different port than 25.
I have one question for you. If your ISP is blocking all those different ports is he giving you reverse DNS? Of not even with
with static address your mail server is useless as any normal mail server will bounce mail from the server without reverses DNS.
