A common convention is that e-mail messages contain a short description of the
author, called "signature" and the start of this is indicated by a line only
containing the two characters "--".
Is this convention recommended or discused in some IETF standard? I cannot find
it in rfc5322.
This convention is very commonly used, but somewhat controversial. Some mail
program assume that text after a line with only "--" in it are signatures,
which are by some mail programs shown, when displaying incoming mail, in a
special signature format. And it is a common mistake by message writers to
write a line with just "--" in it for other purposes than starting a signature.
Every mail writer is not an expert on such e-mail conventions. If IETF
describes this convention in some way, IETF should maybe recommend some kind of
warning to people who write single lines containing only "--" when this is not
start of a signature.
