What's the chances of switching to a mailing list system that doesn't expose your email address to everyone on the list when you reply?
That was inserted by your MUA, Mr. Glennon. Verbatim email address, top posting, full thread quote including all ML footers -- you're doing it completely wrong on your end and ask about the mailing list software?
Anyone has a good resource (wiki, blog) for mailing good practice ? That would be helpful.
