In an average month, I reject 5M-10M e-mails a month.

Most are from bots trying to deliver to (or through) my server, but
don't follow the RFCs for compliance (mostly for RFC822). They don't
make it past my pre-scanner SA-Exim.

For the 50K or so per month that *DO* make it then get fully SA scanned
and then either sorted to spam or plain dumped to /dev/null.

I've been dealing with SPAM and "reject notifications" which exacerbate
the bandwidth used... from "Polite" Systems admins... which should only
notify those that are *NOT* classified as spam, that are
rejected/bounced/etc.

And No Casey you guys aren't missing anything. If our e-mail addresses
are on any "archive" some where web accessible... robot-website-scrapers
will grab your e-mail address and use it for either sending to or
spoofing from.

I gave up trying to "0Bf5C471N6" my stuff as it was more effort than
just dealing with the flood and diverting it.
