The reason that ISPs do this is spam related, but if you did send spam
via your connection the IP address could be used to track back to you.
There are better ISPs that don't block ports.

Another option for you might be to set up a mail server just for your
internal network and have the logs sent there.

You might also look at the ddwrt or openwrt projects to see if their

It wouldn't be that much work. Since you could restrict access to your
network, you wouldn't have to worry about spam, which is the biggest cause
of headaches for running a mail server.
