In fact, I had no problem confirming, as I used the weblink.  It was actual
*posting* I could not then do.

To solve the problem I initially queried about -- and I *did* query
about it in sufficient detail, Bill, for you to not mischaracterize it
here; he wants MM to recognize plushacked subscriptions for "can I post"
purposes, as do I.

Very clever response, but I think it's a response to a "1% of 1%" problem,
and thus not pertinent to this architectural problem.

To recap:

RFE: That mailman 3 permit users to specify that they subscribe with
plus-hacked addresses (and optionally what delimiter character they use),
for the purpose of poster-address validation on lists for which subscriber-
only posting is enabled.
