There is an analogous Perhaps because I'm not a technically-trained person, I did not find the above statement especially clear or helpful. I don't know whether "it MUST pass the MAIL FROM: address" means it must USE that address or pass it by. I raise this question because I've had problems in the past with the folks at ALASKA, when they sent all mail bounces back to the original poster named in the FROM line. That created MASSIVE confusion on my large, active list. People thought that their messages somehow hadn't been posted (in spite of the list's default being "repro"), since they received an official-sounding message from a "postmaster" telling them this. So they then tried to re-send the message, sometimes succeeding and further cluttering up the list, and sometimes getting a message from listserv saying that they'd already posted that message. They were then even MORE confused, and I spent an absurd amount of time dealing with their confusion. So, my question is, what IS the proper way for undeliverable list mail to be handled by a postmaster if the list is Send= Private and there's a REPLY-TO address pointing back to the list? My understanding is that in such a situation bounces should NOT be sent to the address in the FROM line but rather to the REPLY-To address, where they will be rejected and sent on to the Errors-To address.
