I'm not sure what "full SMTP header" means myself, but I'm going to guess
you are referring to the relay points any email takes in its journey from
originator to its end point. I'm also going to guess that since the
email addy can be munged, that any relay point can also be munged. And if
I'm wrong about any of this, all I can say is "not the first time I've been
something, nor will it be the last." As that old gas station commercial
to say, "your mileage may vary." :p
Happy New Year all,
