Hi Ralph,
I just realised that a couple of my recent replies to mailing list posts
went only to the originator and not to the mailing list. Maybe this new
mailing list isn't adding a Reply-To header pointing to itself, or
something??
That is correct. It is something that can be changed, and there has been a long discussion about whether mailing lists should mess with the reply-to header or not.
My mail-program automatically recognizes that xymon at xymon.com is a mailing list, and presents me with a "Reply" (= reply to author) and "Reply to List" (= reply to the list address) button. So it isn't a problem for me. I think that has become much more common over the past few years. (For those who are curious, I recently switched from Mutt to Thunderbird - giving up on the text-only interface after some 25 years).
If you don't have such a feature, the "reply to all" usually works.
I won't say it has been set in stone and won't change, but I want some complaints before I change it.
Regards,
Henrik
