You are sending mass emails to your email lists using a satellite connection? Am I reading that right? That seems a bit hillbilly to me.
A shared server with unlimited bandwidth costs $5-10/mo. Or if you insist on doing things the hillbilly way without an actual server, you can get yourself 5 SOCKS proxies for about $5/month.
Yeah, it's an additional expense, but businesses do have expenses once in a while. Plus you've said that you've already wasted a lot of time on this, so what's your time worth to you? You need an IP that you alone are responsible for and have control over, rather than having to go begging to some random ISPs every time issues like this come up. Trust me, you don't want to continue down this route. I say that as a programmer who has worked for mass "marketers" (that's the polite term) for 20 years.
By the way, I have used AOL mail for a long time (since they bought out Netscape) and I do miss _tons_ of emails. Always have. From reputable big banks, I might add. There is little you can do as an AOL "customer" except get a real email account. It's on my todo list.
