queuing is not needed and would be too much programming overhead for
a spammer. The only thing a spammer would have to do is:
resend spam to his previous target list again after lets say 5-10 minutes.

What me more worries is, that services like yahoo hotmail and msn seem to
have some mystic deals with blacklists - but still allow sending of spam.
