hi, i'm trying to write a plugin which should do the following tasks:
1) Before a message is sent, it's body gets signed and an attachment is being created containing the signature data and the body itself. This attachment is sent with the message. 2) When a message with such an attachment is opened, the signature is verified against the body in the attachment. After successful verification, the original body of the message should be replaced with the verified one from the attachment. Now here's my question: Is it possible in any way to replace the body of a message?
