Somehow I left out a very important paragraph, in that email about -all.

I don't recommend it as some of your users are bound to want to send
from email servers besides google's.  If you're sure that they won't,
however, then it's up to you.

I agree with Lonnie, though.  You probably won't be able to totally
solve this problem with the way email is currently setup.  Best option
is to educate your users that you won't put hyperlinks in your emails,
and won't ask for password/other personal information through email.
Then, don't!
