Both Ghio nyms and Zax nyms require special formating of the body of the message. Also, the message must be encrypted to the nymserver and signed by your nym's key. QSL is designed to understand the requirements and handles the formating and PGP needs itself. The way it knows this is required, it the Nym: header. Your outgoing nym messages must have a Nym: header with the same nym name/email address as is used in your nym's PGP key.
If your PGP key's email address is this:
George Johnson <gjohnson@mixnym.net>Then you nym header must be this:
Nym: George Johnson <gjohnson@mixnym.net>Both Ghio nym's and Zax nym's are handled exactly the same in your messages. See the topic Nym Message Templates for examples of this in practical use.
