If you enable 2-factor authentication on the Google account (relatively
secure one-time password apps won't suffice until you also give them
your phone number; make sure you don't lose your 2nd factor or you're
locked out forever), Google will grudgingly allow you to create an "app
password": a special password that can be given to "unsafe"
applications to let them send e-mail without fully logging into Google.

Otherwise the only way to send e-mail via GMail is to teach Bugzilla to
speak Google's bespoke dialect of OAuth2 [*] and register an API key.
