I don't think so, Mark.  This is an "announce-only" list, and the sender is
non-US, I think on a dialup.  Let's say the sender's IP or ISP is on the
blacklist.  Even though the list mail is finally coming from my server,
couldn't the presence of his IP or ISP in the message headers be enough to
trigger the blacklist?  - john
