Then technically, Verizon is having a problem in that they announce an
auth mech that actually doesn't work ... (Though that *might* change
from one *user* to another.)

Those mails did not only go to the mailinglist's archives, but also to
however may subscribers, some of them possibly being just feeds into
*other* public archives. Note, however, that your log contained not the
actual password but the HMAC-MD5 digest of it and the challenge string;
it's the *purpose* of HMACs that one cannot derive the "key" (password)
from challenge and digest alone.

(And that's also the reason why a server doing HMAC-MD5 needs a
*plaintext* copy of the password *itself* to verify the digest.)
