TL;DR: Paypal is embedding an image into its emails using the "//" shortcut, instead of specifying http: or https:.
This is wrong since it assumes the mail user agent loaded the content from a web server. There's zero benefit to dropping http: or https: in a URL in an email.

What are 2o7.net & omtrdc.net?

Everyone should block all access to 2o7.net, the same as Google Analytics. Nothing useful comes from them.
Use their instant notification API https://paypal.com/ipn to have it trigger a script on your server to notify you any way you'd like.
You get more info from the api too and it's triggered before emails.
