I look at it as a trade space, with "user popularity" traded off against "difficulty of supporting" [the MUA]. Or, perhaps more correctly, the axes are "user popularity" and "ease of supporting." If the score on either axis is sufficiently [1] high, I do my best to support it. Hence, we use three invariant headers: List-ID:, To:, and Reply-To: (yes, we munge Reply-To:, yes, we've covered that discussion in detail, yes, it is a holy war, yes, I have my reasons for munging Reply-To:, and no, I'm not willing to change <g>). On all of my lists, I add in an "X-Message-To: <subscriber_address>" header, to help the Listmoms (thanks, Chuq) handle those cases where e-mail addresses may have changed. And on my largest list, I also added in an Errors-To: header, for those MTAs that still use it. - Vince [1] #define sufficiently we're not likely to receive complaints from users
