2.2m Messages, 1.8m Spam
Since installing our SpamBlock server we have access to detailed statistics about the number of spam emails being delivered to some of our customers, and the figures are truly amazing.
Of 2.2m messages delivered to the system, 1.8m were spam. That’s 82% spam… 82%!
Of these, 201000 are ones delivered to random names at a domain (ie csdwewr@whatever.com) which is one of the reasons we don’t recommend “catch-all” mailboxes where anything@whatever.com is delivered to a default mailbox. It just makes the spammers job easier.
Just over 1m messages were blocked by RBL (realtime block lists) available freely on the internet. When used carefully, these lists are fantastic resources in the fight against spam.
So it seems the solutions are out there to reduce spam to practically zero, but they need constant hardwork to keep them effective - as usual its a constant technological battle between the spammers and the wider internet community.
