What a shame Disney Hotel Swan uses Microsoft hosted servers with wrong configuration

My hotel reservation for Lotusphere got stuck in my potential Spam folder...

There are two issues with the mail according to SpamGeek ...

- The MessageID does not contain a valid domain -- OK that is the fault of the application sending the confirmation mail.
- The server sending the mail used the wrong Domain in the HELO command (does not match the IN-ARPA)

I got some offline comments about this post.

Yes I agree both are not really breaking any RFCs but there are best practices for well configured systems.

You don't have to specify a vailid Domain in the message-id but it would be a good configuration.
