Publish Certs to Global Address List

We have Exchange and our domain   Users are setup to retrieve in this domain e-mail in outlook. We have some users internally here that have IMAP e-mail boxes set up in outlook as well. These IMAP accounts are for another organizations domain. These users have need to encrypt/decrypt and digitally sign e-mail. The only way we have been able to get this to work is to have the potential receipient send our users a digitally signed e-mail. Our users then use this e-mail as a template to send additional e-mail to the potential receipient in the future. Is there a way we can publish digital signature certificates for the other domain to our Global Address List?

    This would require a few steps and may not work in the end. :)

    1. Create a user account for the remote folks in your AD (using a local address).
    2. Create a contact in AD using their real address.
    3. In the user account, deliver all mail to the contact.
    4. The other organization needs to send you their certificates in base 64 DER encoded. Then in your DSA, AD users and computers, enable advanced features, go to that user. Import the certificate on the certificate tab.

    Then send signed/encrypted mail to the user (the contact should be hidden as well). I am pretty sure, but not absolutely positive, that will work.
