Point taken. If list-ID exists, it is what you should use to filter list mail on. not all list servers support list-ID yet, but the right answer is to encourage them to follow the standards, and you should.
Not to sound like Mr. Negativity, but your proposed filter on List-ID isn't implementable on many mainstream MUAs. So I have seen this question asked already, but read no response so far - I use Outlook as my MUA, so how do I sort on the List-ID field (impossible from what I know of Outlook)? From what you appear to be supporting I have two choices - be screwed or change MUAs - neither are acceptable answers from my standpoint.
I also have the issue of seeing the mail headers reflect that the mail was sent to me and CC'd to the list, especially since the from line states your name and not the list name. This isn't correct (read as wrong!). I did not receive the mail directly from you as indicated based on the painly visible header fields. The original mail was not CC'd to the list as indicated either. In fact, it was mailed to the list and distributed from the list to me. Maybe this is a semantic, but it's how folks see and read the To, From, CC headers - including myself. Creating this kind confusion and making it harder to relate to how a mail comes to be delivered is not a standard that I believe will gain support. If you think folks want to spend their time examining headers to understand how the mail was really handled, then you're on the right track here. But if you really understand end users, you will know better. Now, did I send this mail to you directly or did it come through the list? Would you know for sure if you hadn't filtered it without digging through the headers? I believe my point has been made if you think about it a little.
I've been doing email for over 23 years now and I've never seen this kind of header mutation come to be accepted and I really hope Mailman doesn't keep t his adaptation. I think it is unacceptable to alter the headers this way - just my two cents.
Thanks for the listen, Mike
