Is there some way of determining if a given Yahoo ID or email in the contacts list is valid, or in an email has ever bounced to a specific address, for that Yahoo user?

Bounces hurt my reputation with Return Path and other email providers. I would like to avoid trying to send email to an address at Yahoo (and hopefully other places) which Yahoo knows to be invalid.

I'm allowing users to select from their contact list (which I fetch with the Contacts API), but sometimes the user chooses an address which is invalid. I send the message for them from my mail server, and I receive a bounce, but it would be good to know in advance that the Yahoo ID is not valid, or that perhaps they have tried to send a message to this email before with their Yahoo account and have received a bounce in the past.

One alternative I can think of is to provide a page on my site to allow them to send the message through their own Yahoo Mail account, using the Yahoo Mail SendMessage API call. That way Yahoo receives the bounce instead of me. However I'm a bit hesitant to do that since I would have no way to track the message. Is it a good idea?
