What I do is add a 60 second delay before sending them the error code.
It's not the bandwidth that's important, it's the number of emails per
hour they send that is.

This would negatively affect mailing lists and other regular senders.
It would be bad for each new message to get delayed.  What we want is
for the regular senders to be impacted as little as possible.
