As a follow-up question...

Would it be possible to also check the name of a distribution list in the "To"?

For example, we have To: Bob (which is a distribution list to robert@hotmail.com and sally@hotmail.com). We have Subject: Personal Information Bob. We have the attachment "Personal Information Bob.txt". Can we add a check that the distribution list is named or contains "Bob"?

Thanks again,
Andrew

UPDATE:
Thinking it through a bit more, it would be good if it could perform the check if the To is a distribution list. If the To is not a distribution list (that is, just an email), then perhaps throw up a prompt that says, "You are attempting so send an email to X with an attachment named Y. Do you want to continue?" And then allowing the user to either send or cancel. Is this possible/feasible?
