This reminds me of all the emails I received from roots due to putting an actual address of mine in the receiver field of a Postfix guide I wrote years ago. People will blindly copy paste whatever text you put in tutorials.

Something that I’m surprised a lot of devs don’t know; there are official domains you’re supposed to use for documentation, testing, etc. They are specifically reserved by IANA for these purposes. Originally I think it was just example.com, but they now have a list of all them: https://www.iana.org/domains/reserved

Not just domains but IP address ranges as well. Doesn't stop lots of people from doing things like using real US DOD ipv4 /8 sized ranges for things they shouldn't.

Note that `foo@bar.com` is frequently used to get around the email address requirement, so it is not really for testing. I wouldn't be surprised if prominent websites block any address from example.com or so.

this makes me wonder about what volume of mail an MX for contoso.com would receive, if microsoft didn't own the domain. https://www.google.com/search?client=ubuntu&hs=ujt&channel=f...

contoso.com does have MX records.

    $ dig +short -t mx contoso.com
    10 contoso-com.mail.protection.outlook.com.
