Hi,

Recently, I sent out patches which were fixed up with --amend on older 
commits. When I sent them out, the patches contained
     Date: <more than 2 days old datestamp>
in the headers. Now, sending these mails is fine, and mail clients 
generally handles it perfectly fine. However, after doing this I got 
an email from postmaster@vger.kernel.org, basically telling me to not 
do this, since they get a lot of bounces where the return is marked with
     Diagnostic Code: smtp; 550 (4.5 DATE_IN_PAST_48_96 Date: is 48 to 
96 hours before Received: date)

This is understandable. The question is, do we fix the tools to handle 
this, so that emails are always generated with now() date, and the 
commit content contains a tag for the original commit; or do we simply 
say, always send patches to the mailing list with a current timestamp?

Maybe my workflow is incorrect too. I don't mind pointers on this.

I guess rebasing before generating the patch series would have fixed 
this, but I really didn't need to. I simply reset HEAD~2, fixed with 
--amend, then cherry-picked the other on top again; then created the 
patch series.

I think the right solution would be for send-email to move Date: to the
beginning of the body part, just like it adds an extra From: there when
the sender is different from the author, and not lie about the mail
transmission date.

Then we won't lose the authorship date information in the resulting commit
and will still keep the mailpath happy.
