If message headers and footers are so popular, how do you explain the continued "please

hesitate to remove them when I made my mailing lists DKIM compatible.
Also while it's certainly true that subject prefixes are popular with list
operators, I didn't hear a single peep from my list users when I removed them.
I doubt anyone noticed. Granted, mine is a small sample group of a few hundred
mail server operators, but I would have expected *someone* to notice.
I've been surprised how many otherwise-technically-competent people use
subject tags to filter mailing lists. However, I suspect much/most of
this could go away if MUAs started displaying List-* information in a
useful way, and made filtering on those headers easier than the Subject
header or the To header.
Either way, if message footers and subject tags have to go away and that
gets us DKIM signatures through mailing lists (which seems to mostly be
possible now), that seems like a step forward.
On the other hand, it's only a matter of time before some idiot DKIM
signs the (lack of) List-ID or List-Unsubscribe header while using a
DMARC reject policy, resulting in the list engine damaging the DKIM
signature. I'd class this as abusive and ban such posts from any list I
operate, but no doubt it's only a matter of time before it happens.
