Does anyone have any ideas or just point me in the right direction?
I'd say: Forget it. You can't find out whether an email address is
deliverable without asking the mail server of that address, i.e.
trying to send a message. What you can do is testing if the
domain/host has an MX record. And you can of course test the syntax,
but that's it.
Why don't you just send a message and ask the recipients to confirm
that they are still reading their messages to respective address?
Because you are not going to send any unsolicited crap anyway, right?
