Message is transformed

RFC822

The Encrypted: header is used to describe a translation that has been performed on the body of the mail message. Although encryption is implied , other forms of translation, such as compression and uuencode (1), are perfectly legal.

The sendmail program ignores the Encrypted: header. This header is intended for use by MUAs. Unfortunately, most (if not all) Unix MUAs also ignore this header. The form for the Encrypted: header is:

 Encrypted:  prog key  

The field contains one mandatory item, the prog , and one optional item, the key . The prog is the name of the program that was used to transform the message body. The optional key is a decryption key.

If translating the message body into a different form, be aware that many versions of sendmail strip the eighth bit from all bytes of the body during transmission.

The Encrypted: header is deprecated and was dropped from RFC2822. The Encrypted: header should never be declared in the configuration file.
