perhaps not that, but surely [email protected] and if they do/have auth

1) monopoly isps
2) standard config
3) lack of ability to make 1/2/3 changes here/there/everywhere (config
drift) for customers not paying more than the 'standard'.

SMTP/IMAP services COULD just do tcp/587 'submission'... but we covered
that ground already I think?
