I like pulling $DATE from the messages in procmail.


Just a nitpick: many spam messages come with wrong dates, sometimes
*years* off. Depending on what you want to use the value of this
variable such dates may be undesirable.

No, I think you misunderstand.  My procmail is invoked with the
"-f-" option in .forward, which causes procmail to rewrite the
From_ header.  (One reason is that I live in a different time zone
from that on the processing host.  I want the receipt time in the
From_ to show my TZ.)  The time that is written there is from
the local host -- not from the Date: header!

 From "man procmail":

       -f fromwhom
            Causes procmail to regenerate  the  leading  `From  '
            line  with  fromwhom as the sender (instead of -f one
            could  use  the  alternate  and  obsolete  -r).    If
            fromwhom  consists merely of a single `-', then proc­
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
            mail will only update the timestamp on  the  `From  '
            line  (if  present,  if  not,  it will generate a new
            one).

In fact, one of my very good spam snags is to compare the From_
header's time with that in the Date: header.

This topic has had lots of discussion over the past couple of years,
so the curious might want to hit the archives . . . .
