Ok, the line :
>From [EMAIL PROTECTED]
IS WRONG in the RFC822 mean. this is right :
From: [EMAIL PROTECTED]
and here we have to agree because it's too simple. this comes from 822
3.2. HEADER FIELD DEFINITIONS
These rules show a field meta-syntax, without regard for the
particular type or internal syntax. Their purpose is to permit
detection of fields; also, they present to higher-level parsers
an image of each field as fitting on one line.
field = field-name ":" [ field-body ] CRLF
field-name = 1*<any CHAR, excluding CTLs, SPACE, and ":">
field-body = field-body-contents
[CRLF LWSP-char field-body]
field-body-contents =
<the ASCII characters making up the field-body, as
defined in the following sections, and consisting
of combinations of atom, quoted-string, and
specials tokens, or else consisting of texts>
and it is not MTA responsibility to add the "From: ..." line. it's MUA
responsibility. the only header the RFC821 ( and updates ) require from
the MTA is the "Received: ..." line.
