Hello!!<br><br>I'm running a system with a notes connector hanging off exchange. I want to bin the connector and use LDAP for the directory listing and use an SMTP gateway for transmission. That I can do. I've set up Key management and have got this working but will want issue certificates to and from exchange and Notes....I'm looking into MS Certificate Server but my brain is turning into mush.....can someone shed any light on the best practices for encryption and certification via an smtp gateway, rather than a trusted domain.<br><br>many thanks
