RE: Nice New List... Still can't Post via Email.
We Do! I would say your post is successful. 😊
My problem was...
When you post to the list, the Debian mailing-list server does a connect-back to the authoritative mail server for your domain name, in my case that's 'jaruzel.com' for @jaruzel.com. It then tries to validate the sender's address by doing this over SMTP:
MAIL FROM: <>
RCPT TO: <email@example.com>
My mail server is a home-grown system (for various long winded reasons), but when I built it, I must have missed the bit in the RFC where '<>' is a valid 'MAIL FROM:' address. My mail server barfed, and Debian mailing-list server decided I was a fake address and killed my post. I patched my mail server code to accept '<>' and now it all works wonderfully! A unique case, but very very annoying.

Let's see if I can. I haven't made a post since the move.
We'll know soon enough, right?
