SMTP error from remote mailer after RCPT
TO:<rossiestreettddx@???>:
host popstar-com.mr.outblaze.com [205.158.62.33]:

That's right - these are all spams forging random addresses on our
domains, and then we get nearly saturated with bounces hitting our MXs
:(
Have to find some way of trashing / bouncing all these bounces (sendmail
8.12.x) short of rejecting MAIL FROM:<> ...
Try spamassasin or something (or maybe open proxy dnsbls) rather than
sender verify callouts - I would rather not have further unnecessary
connections to our MXs at the moment, thankyouverymuch.
