12.13 Date:
The origin date RFC2822
The Date: header specifies the date and time that the mail message was originally sent. All
mail messages must include this header line. Consequently, the Date: header must be
declared in the configuration file like this:
H?D?Date: $a
The $a macro (?§21.9.2 on page 802) is mandatory in the field for this header. The value in
$a is the current time in RFC2822 format. (See Section 5.1 in RFC2822 and Section 5.2.14
in RFC1123.) Only the $a macro should be used with the Date: header because it is the
only one that is guaranteed to contain the current date and time in RFC2822 (and
RFC1123) format.
The ?D? flag is always included withth e Date: declaration in the configuration file. All the
standard delivery agents always include an F=D flag (?§20.8.22 on page 769). The ?D? allows
custom delivery agents to be designed that do not need a Date: header.
25.12.14 Delivery-Receipt-To:
Like the Return-Receipt-To: header Sun Internet Mail System
See the Return-Receipt-To: header (?§25.12.34 on page 1165).
25.12.15 Delivered-To:
Mark a mailing list expansion qmail
The qmail program uses a Delivered-To: header to trace all the alias and mailing list expansions
through which an email message passes. This is similar to the way Received: headers
are used to trace machine hops. When qmail expands a mailing list, it adds a Delivered-To:
header to the top of the message:
Delivered-To: list@host
If an identical header is already present, qmail bounces the message.
