  Usually, the concern with distributed messages is where the message 
appears in the summary of the recipient's e-mail client.  Moderated 
messages may have been sent hours or days before the time of approval 
and distribution.

  I believe most email clients are configured to display a summary of 
the most recently dated messages.  Unfortunately, this doesn't reflect 
which messages were most recently received.  Someone who receives a lot 
of email may not notice the newly distributed email because of the date 
it was originally sent to the list.

  Maybe leaving the date unchanged is a common behavior for most 
mailing lists, but we've been using Lyris list manager for almost 9 
years and most list admins have chosen to change the date to the time of 
distribution.   For this reason, I think it is safe for us to roll out 
Sympa with all lists set to change the date using the method provided.

  I agree.  The archived message date should remain unchanged. 
Preserving the original message is important.
