I don't know - see if you have a 'view headers' or 'view source' option in your
favourite webmail client.
<pedantic hat> the mail isn't a 'web
mail'. there is nothing special about it, other than it's viewed / rendered /
shown in your computer via a webpage. Whether yahoo/gmail/hotmail systems get
rid of (certain) headers when they store the email, i don't know.

As above, is the date header ('Date:' ) added at the time of sending by the
sending party. Trivial to forge ( have you ever received an email , from
spammers or clock-deprived people that was sent in 1980? or 2015 ? :) )

The former, assuming it hasn't been tampered with.
