Several people kindly contacted me off list with laborious
explanations of how to implement delayed 550 rejections using
sedmail, et al. We gave up sendmail years ago in favor of a
competing solution.
I haven't seen any succinct justification for providing a
550 message rejection for positively-identified spam versus
silently dropping the message. Lots of how-to instructions
but no whys.
