I can feel for your situation, as I fought a similar problem in the Philippines. It appears, since you can send via your postfix, that your providers do not block port 25 (my ISP did). Though I don't have one, it might work to get a gmail account and use their authenticated smtp server as your postfix relay with all your dial up accounts. Someone in this thread mentioned they have authenticated smtp, and if your providers will allow the connection, it makes a way for you to be able to send from an IP block/provider that should keep themselves off the RBLs.
I wonder if they will for long. I just received one spam that scaped SA with a return address in gmail. That was one of the reasons to include a server into blocking lists... -- Cheers, Carlos Robinson
