I guess you could loop thru them and apply a regexp to see if they were
[seemingly] syntatically valid. This still wouldn't catch an address like
[EMAIL REMOVED] though.

You could also telnet to the host to see if it responds, possibly on the
right ports. That obviously still doesn't mean that the mailbox/user exists.

It's very problematic whatever you choose.
