Bulk mail is still expensive, and it is easier for the scammers to send e-mail
then to try and get a bulk mail piece past the postal inspectors.
Looking at my stats for the year, At the beginning of 2008 I was rejecting (at
MTA) less than half a million messages a month. Now it is over 2 million a
month. That is pre-processing rejections on a system with less than a hundred
people on it. I can imagine what you ISP level guys are dumping!
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
