I’ve been running a more aggressive anti-spam and anti-virus regime on my inbound mail servers for about six weeks now.
The statistics are interesting; inbound spam outnumbers ‘real email’ or ham by around 2:1.
This means that during any day there are at least twice as many unwanted, spam emails – as opposed to real mail. That’s unwanted bandwidth usage and unwanted costs for me! If I wasn’t filtering and capturing this then I would have to be more alert to unwanted emails and delete them.
I’m also using ClamAV to check for viruses within email attachemens. Typically around a dozen or so viruses attached to mail per day. Captured upfront.
