75 messages so far today from paypal.com, all of them passed dkim
signature check in both exim libraries and spamassassin. If you wish
to compare source addresses, here's a snipped from one mail server:

# grep paypal.com /var/log/exim/main.log | grep \<= | cut -d \ -f 6-8
| sed -e 's/P=esmtp//' | sort
