An authentication mechanism - and a not very good one - called "sender
policy framework"

Some internal tracking header included by yahoo, probably part of their
spam scoring to decide whether an email should land in the inbox or the
spam folder.

The connecting IP address to the server ..  quite often it is the IP
that you used to login to yahoo - or the proxy that you used.

Another (rather better) authentication mechanism, DKIM.

This and the other received lines trace the path your email took to get
from your email program to the list and then to the recipient

The x-yahoo and x-ymail headers are headers inserted by yahoo for their
own internal tracking of message traffic

Part of the mime structure of an email .. says that it is "inline" - no
attachments, or if there are any attachments they are included in the
message body rather than as separate attachments

These two are headers inserted by spamassassin which sourceforge runs
for hteir spam filtering.

X-Been-There is a header mailman inserts, to prevent messages going into
an endless loop (from the sender to the list to a recipient and sent
right back to the list by some account misconfiguration etc etc).  If
mailman sees an incoming message with that header it wont submit it.
