how can i use S/Mime encryption/decryption with an domain certificate but only with one external partner (other domain)?
Emails to other recipients must be encrypted with their personal S/Mime certificate.
With kind regards
Does anyone have any thoughts on whether it is possible to create or modify the Ciphermail internal certificate authority to be a authority subordinate to an existing enterprise PKI? Perhaps after creating an internal authority the intermediate certificate could be manually substituted with one created from the enterprise PKI using shell commands?
