A little off the MI topic, no? <G> Anyway, "X-Mailer:" described the mailer software used to send the message. Very little is mandatory in the SMTP message header and I'm not aware of _any_ "X-" headers that are mandatory. The idea of the "X-" prefix is that this is a non-standard extension. Of course some "X-" extensions have become defacto standards, but none of them are mandatory. If you're sending mail using your own software you're free to make X-Mailer appropriate for you. We use it in one of our products to indicate that the message came from the product and what version. "X-" headers are great for storing all sorts of things about the message, think of them as the SMTP version of the META tag in HTML if that helps. -Walden ------------ Walden H Leverich III President Tech Software (516) 627-3800 x11 (208) 692-3308 eFax WaldenL@xxxxxxxxxxxxxxx http://www.TechSoftInc.com Quiquid latine dictum sit altum viditur.
