Abstract
An email request is received from a client device, where the email request is intended for an email server and includes a request for an email recipient's certificate. The compliance status of the client device is obtained. If the client device is in compliance, the email request is modified, and the modified email request is sent to the email server while a certificate retrieval request in the email request is redirected to a certificate repository implemented in a server separate from a certificate repository maintained by the email server. The email certificate is retrieved from the certificate repository and combined with information received from the email server to generate a response, which is sent to the client device.
