We have a 3rd party vendor that is currently using Microsoft Outlook/Exchange and wants to send us encrypted email. They are generating the certificates from the Microsoft Exchange server and sending them to us. They send us an unencrypted email with the certificate as an attachment in the email. After we receive the email we go to Tools/Add Sender to Address Book. If I am understanding correctly, this should have been all we had to do to accept the certificate. When they send us an Encrypted email back, we are unable to open the email. I was wondering if there should have been anything else that I needed to do? We are running an r6.0.1 server with a mixture of r5.0.11 and r6.0.0 clients.

There are several things to check. First, did you send them your public key? You need exchange keys for encrypted email to work. Second, make sure your person record is set to “No Preference” or “Prefers MIME” for your Message Format. No preference is the better choice. Make sure your client location document is set to send Internet mail in “MIME format” as well. Finally, make sure your server based Domino virus scanner isn’t stripping out the certificate when it scans the message.

The preferences are set the way you described. We are not able to open the encrypted email when they send it to us. I can’t prove that the certificate has been accepted by Notes enorder to open the mail.

All you can do is make sure your people have the sender in their personal address book and the X.509 certificate is present in that record. You can find it on the advanced tab. If it isn’t there, then you won’t be able to read the message. If it is there, you should be fine, as long as the sender has properly received your X.509 certificate and is encrypting the email properly on their end.
