[RFC] mda: use PublicInbox::Address to extract emails

[Eric Wong]

I'm not sure why this wasn't done in Jun/July 2016 when I was
working on PublicInbox::Address to replace the DoS-vulnerable
Email::Address.

Nowadays, PublicInbox::Address allows using Email::Address::XS
which should be fast and robust.
