It=92s a signature and info about the data that follows. In C it=92s a:

struct {
        char[8] preamble; // =3D "A54E57460D0A1A0A" in hex; starts =
"=95NWF" in=20
ASCII
        long length; // of the data following this header
        short checksum; // not used by SimpleMail / Mail V; =
always 0
        short unused;
};

This header is used by EnRoute=92s inet, and SimpleMail/MailV generate =
it=20
only for compatibility, so you can mail packages between the two=20
transports. The data that follows is a NSOF flattened frame containing=20=

the message.

I hope this puts your mind at rest.
