Spam

Spam has been increacing and I have started to find it is reaching hte point where spam exceeds not only proper mail (it achieved that mark a long time ago) but also all other traffic - by a huge margin. What that means is most of the bandwidth that we spend pays for mail that our filter will block.
Not a problem?

Well imagine what happens if every spammer/advertiser in the world can send mail to basically everyone in the world in one go. then each person gets a hundred million odd messages per cycle from these guys - possibly in multiple different versions. Now our filters and processing power MIGHT be able to keep up with this but can our bandwidth?

It will be particularly annoying in places where internet conenctions are not so fast.
