Since none of Uma, Wendy, or Violet implement DomainKeys or even know what
they are, DomainKeys accomplishes nothing.  OTOH if their { ISP, company,
whatever } has STARTTLS enabled, they're getting their email encrypted without
even knowing about it and are having better-than-average security applied to
their POP/IMAP mail account, again without even knowing about it (I suspect
the latter is far more of a selling point to users than encryption.  No-one
would want to read their mail anyway so they're not worried about that, but if
it stops those nasty hackers from breaking into their account, it's a good
thing).

He'd instead need to spend even more time mucking around with keyrings and
updating keys and writing scripts to handle all the checking and wondering why
it all has to be so complicated, and maybe he should just ask people to fax in
submissions.
