Would you pay for a 1Password-like service for email?
there: interesting idea.  a few issues come to mind:- people concerned enough about privacy to use such a service might have concerns about their emails being passed through your service as well.- the domains of that service might get blocked on certain sites due to abuse and people using multiple email addresses to create multiple accounts.- spam filters might block the inbound emails because the 'to' address doesn't match up to the user's.  though i can't imagine many would place a high probability on this metric since mailing lists and such would act the same way.
