What do you want to edit? What are you trying to hide?
==========================
In some cases, I would like to add the List-ID header specified in RFC 2919
(see http://www.faqs.org/rfcs/rfc2919.html )
In some cases, I would like to add the standard headers specified in RFC 2369
(see http://www.faqs.org/rfcs/rfc2369.html )
Finally, in some cases, I would like to add some X-Fields (X-Headers or User
Defined Headers) in the header info.
Some side notes on User Defined Headers:
RFC 822 (see http://www.faqs.org/rfcs/rfc822.html) provided for "user defined
fields" in email headers. The RFC said:
==========
4.7.5. USER-DEFINED-FIELD
Individual users of network mail are free to define and use additional header
fields. Such fields must have names which are not already used in the current
specification or in any definitions of extension-fields, and the overall
syntax of these user-defined-fields must conform to this specification's rules
for delimiting and folding fields. Due to the extension-field publishing
process, the name of a user- defined-field may be pre-empted
Note: The prefatory string "X-" will never be used in the names of
Extension-fields. This provides user-defined fields with a protected set of
names.
==========
Note that "X-" is a reserved string to enable people to create their own user
defined fields, without worrying that these fields would conflict with any
standard fields. These are sometimes called X-Headers or X-Fields.
RFC 822 has been obsoleted by RFC 2822 (see
http://www.faqs.org/rfcs/rfc2822.html). And, unfortunately, RFC 2822 did not
include the specification of X-Headers. This "flaw" in RFC 2822 has been
commented on in several places on the net. (See, for example,
http://archives.neohapsis.com/archives/postfix/2003-05/1654.html )
Nevertheless, the use of X-Fields or X-Headers remains common.
