[PROPOSAL]: Date header and Queued messages

[PROPOSAL]: Date header and Queued messages

[Xavier Maillard]

[-- Attachment #1.1: Type: text/plain, Size: 1410 bytes --]

Hi,

Why do we put the 'Date' header even if the message is pushed into the
queued group ?

For my case it result to something quite annoying since I write my
mails when I am in the train and can't send them before the evening so
it generally result in something with 14/15h late !

Can't we just set this header when the mail is really sent (ie:
dequeued and sent) or at least remove the header when sending it.

I have personally thought to this a long time ago and I am currently
thinking it would be better to do this way. 

My current proposal is to remove the header in `gnus-draft-send`
function if we can ensure we can regenerate the Date header after
otherwise just pass through ;)

So I did something quite simple and it works perfectly for me (I have
been using it since a week now). So in case it is of interest by one of
you, I have enclosed a very small patch that just does the trick.

Any opinion ?

I know I can remove the "date" header just by editing the queued
message again but it is obvious for me to edit all of the queued
messages just to send them with a correct date header.


Regards,

zeDek

P.S: since the patch is really small and given the fact I still do not
have sent my FSF copyrights assignment papers, I hope you will able to
add this upstream otherwise be sure I will send them (the papers) on
Saturday.

2822 has this to say on the semantics of Date:

,----
| 3.6.1. The origination date field
| 
|    The origination date field consists of the field name "Date" followed
|    by a date-time specification.
| 
| orig-date       =       "Date:" date-time CRLF
| 
|    The origination date specifies the date and time at which the creator
|    of the message indicated that the message was complete and ready to
|    enter the mail delivery system.  For instance, this might be the time
|    that a user pushes the "send" or "submit" button in an application
|    program.  In any case, it is specifically not intended to convey the
|    time that the message is actually transported, but rather the time at
|    which the human or other creator of the message has put the message
|    into its final form, ready for transport.  (For example, a portable
|    computer user who is not connected to a network might queue a message
|    for delivery.  The origination date is intended to contain the date
|    and time that the user queued the message, not the time when the user
|    connected to the network to send the message.)
`----

It says it is "not intended to convey the time that the message is
actually transported", although I can see how some of the other
wording can be read as meaning something else -- by using the argument
that the queue might not be the "final" form of the message, since you
can edit messages in the queue.

Further, having the Date: header say when Gnus sent a message through
SMTP or /usr/bin/sendmail make it impossible for the receiver to find
out when the message was created.  The time the message is sent is
visible in other headers already.

My vote is for keeping things as is, so that Date: indicate when you
finished creating a message that is eventually sent.

Perhaps if you edit a message in the queue, it should replace the
Date: header.  Maybe it already does.

But it should be simple to achieve the behaviour you want, via some
hook.  I couldn't find any appropriate hook.  Perhaps replacing the
code in your patch with some code that invoke a
gnus-agent-send-queue-article-hook or something.

How can that possibly matter to the readers of your email messages?

That would be my vote too.

I vote to Xavier Maillard.  Gnus is fully customizable, isn't it?
I regard the proposal of RFC2822 as nonsense.  Even if he
violates it, nobody is troubled and nobody notices.

Of course, he can do what he wants to do using some hooks, e.g.,
message-header-hook, maybe.

If the patch gets installed, removing of "Date" should be customizable
(defaulting to the current behavior).

And if there's no suitable hook yet, we could add one.

BTW: Xavier, why do you set the IS-REGEXP argument of
`message-remove-header' to `t'?  It should be nil, IMHO.

+      (when (memq 'Date message-required-mail-headers)
+        (message-remove-header "Date" t))

Additionally, your code also applies to messages from "nndraft:drafts"
when sent with `D s' (gnus-draft-send-message).  If there already is a
date header, I don't think it's a good idea to remove it in this case.

Bye, Reiner.

My guess is that 'gnus-draft-send-message' actually calls
'gnus-draft-send' function. So normally it should not matter.

Yes.

?  When a user has set a Date header in a postpone message, it should
_not_ be removed, when the message is finally sent using `D s'.

Not the readers but me :) In fact it doesn't matter that much but I
find it more convenient and I almost fear people won't see the messages
I post when the date header is quite old (ie 2/3 days old).

If it is just a convenience to you then a local hack via some hook
would be more appropriate.

That's also my opinion.  Hooks at neraly every stage of e-mail
processing exist.

I totally agree here.

I often write messages at night and only send them the next morning,
bypassing additional emails (often from other timezones). Specifying
the time the message was actually /written/ allows the receiver to see
that I could not possibly have known any information sent later.

IMHO it should:)

Hmm yes, I see your point. It is valid (at least it seems to me) and I
must admit I didn't think about that :)

Ok now I think I clearly don't want Date header to be overloaded when
_really_ sending mails ;)

Thank your for this explanation

Perhaps because the message is regarded as "done" when it's queued? In
view of what rfc 2822 says...

Especially when you see that messsages saved in drafts, do not get a
Date (they aren't "done")... a logical difference between messages in
'drafts' and in 'queue'. Does it make sense?

(Maybe that could be another solution in your particular case: Save
the messages in drafts and then send them all when connected (D S)?

I've used that when I've written something late at night and didn't
feel like revealing that O:-))

Yeah i was not aware of that point. I do not think my mail exchange is
done when I just say 'Send' I considerate it is done when I press
'Send' and gnus is effectively plugged.

I was talking about 'queued' messages that *do* have a Date header (for
sure).

Yeah maybe but my problem is I keep 'templates' of mails in my draft
group so it may be a problem ;)

So do I :) It is one of the point I wanted to modify because my
