bug#41102: When messages have no Date:

[積丹尼 Dan Jacobson]

Got an idea: if a mail arrives without a Date: header, gnus should add a
X-Gnus-Artificial-Date: <now> header.

And when opening such messages, if no Date: is found, use the
X-Gnus-Artificial-Date: header when making dates for the *Summary*
buffer.

That way instead of 1970 dates, you'll have dates certainly just a day
or two from the real date (when they sent the mail, that we don't know.)

-AND/OR-

Dig the earliest date out of all the Received headers.

My idea increases the accuracy of the date thousands of times over
"1970" (which of course could still be an option for folks who like it.)

bug#41102: just like totally-fudged-out-message-id

[積丹尼 Dan Jacobson]

Just like
nnmail.el:  (concat "<" (message-unique-id) "@totally-fudged-out-message-id>")
Make a X-Gnus-Totally-Fudged-Out-Date header.

bug#41102: Add a X-Gnus-Note

[積丹尼 Dan Jacobson]

Or make a standard
Date: <now>
but also add a
X-Gnus-Note: Date header added by Gnus

bug#41102: Mutt

[積丹尼 Dan Jacobson]

Let's have a look at what mutt does,

q:Quit  d:Del  u:Undel  s:Save  m:Mail  r:Reply  g:Group  ?:Help
        1   +  5月 06 國有財產署      (0.4K) 請回填信件驗證碼
        2 N F  5月 06 To jidanni@jida (0.1K) test

Well the first message is the one with no date.
As we can see mutt doesn't say 1970.

I don't think we should pretend -- when we don't know what the sent date
is, then giving an errorish date (1970, aka year zero) is the best, I
think.

So I'm closing this bug report.
