ARRRGH! I have fought with more ISPs about that. Null Return-paths are
specifically permitted according to paragraph 3.6 of RFC821. It is most
annoying to hear that BrightLight, after months of fanfare, cannot produce
an RFC-compliant product.

Not personally. However, I've tried MailShield, and recommend it. It was
developed by the same folks who developed the "Lyris" list server,
so it's quite compatible with list servers. Might want to consider
suggesting it to Concentric: <http://www.mailshield.com/>. The usual
disclaimers apply (except that I do run a bunch of my mailing lists at
lyris.net -- but that wouldn't exactly motivate me to recommend MailShield
if I didn't think it was a great product).
