That's an authoring question, so even more off topic.  The basic 
question was off topic, because this is a HTTP issue, so an IETF one, 
not a W3C one.

Competently produced dynamic web content (not just HTML) has a 
dynamically generated Last-Modified header.  Unfortunately most web 
administrators are lazy or don't understand the web server well enough. 
  Also most content providers are not interested in providing accurate 
dates, and in particular are not interested in providing accurate 
cachability meta-data (they would simply prefer that the resource never 
be cached, because they do not value caching over the user predictably 
getting the very latest content).

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
