HENRIKTEKNIK  This is brilliant. It bridges a gap between the Address Book and Mail. And it does it without any problems or hickups.

Thanks!

ENDE42  Nice! Does what it says. Just set up a addressbook group 'Mailboxer' and run Mailboxer from time to time. Just remember: If contacts in your AB change mailaddresses, you wont see the old mails in the smart mailboxes any more.
