Are you saying that it's better for users not to know that their mail
has been delayed?  It's better for them to assume that it arrived when
it really hasn't?

If folks run around in a panic, then it's a training issue, not an
excuse for you to quell useful informational messages.

Again, I have many _very_ strong opinions on how email should be
managed, this is one of them.
