If you allow your password to expire, you will not be able to receive email

Not having access to email wouldn't be so bad, really. 

What I love is the confirmation message at the bottom. We've just told you to change your password. Someone has changed your password, but we don't know who. We hope you do.

Interesting that there are no actual password rules here, only expiration warnings.  

Your password will be automatically reset

Why should I change the password as soon as possible, if it doesn't expire for 10 days? 

Your password will expire in 10 days

I'm collecting expiration and password policy information. Have you received an email like this one? Send it on! Let's collect them all!

(I won't show any personally identifying information or company/organization names.)

I love that getting an error message is step 13.
