"Or why when setting up an email account does the mail app send the domain name you enter to apple?"
It's so that IF your domain is one that is known to Apple, they can reply back with the correct IMAP and SMTP server settings, allowing you to not have to enter those things. If you are in a big company, or use a very popular email provider, this is a help if Apple happens to know the correct settings for your domain. If you are in a small company, not so much. But there's nothing sinister about it.

The graphs you two are arguing about are apples and oranges. One is a graph of temperature readings, the other is a graph of temperature anomalies. They also cover different time periods, and have different vertical scales. I should also point out that the anomalies graph quite visibly dips downward after the year 2000. Just saying. It cannot be argued that there isn't a 'pause' in the warming. It cannot be argued that temperature co-relates poorly with CO2 levels. What can be argued are the reasons why this is so.
Never trust an operating system.
