I am not sure how to do it from the openssl comand line but it can be done in code. If you are encrypting an email the only information that can be pulled from the PKCS7 is the serial number of the cert that encrypted the message and the Issuer DN of the cert the encrypted it. You can then check this information agains your certificates to find out what cert was used to encrypted the message.
