They don't collect email because that's behind a password protected access if it is web driven and presumably imap or pop if it isn't. So your emails are not stored by the IA.

I don't speak on behalf of the archive nor am I in any way associated with it but from a technical point of view the archive crawlers simply do not have access to your emails.

See the faq for lots more information:
