We are using our Ironport IEA machine to SMIME encrypt/decrypt mailmessages to specific domains. The messages are coming from our C650 mailgateways and are send to our C650's back after encryotion/decryption. Our customer wants the subject modified ([Encrypted by XXX}/[Decrypted by XXX). I know I can do that on our C650 by a message filter. Is there a way to do this on the Encryption Appliance or an easier way on the C-Series ?
