RE: [MI400] X-Mailer in MIME

["Walden H. Leverich III" <WaldenL@xxxxxxxxxxxxxxx>]

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.

What does "X-Mailer:" stand for in a MIME header?  Is it mandatory?
