Well we’ve officially surpassed the 2500 emails/day mark at work. I’ve been watching the number creep up to 2500 over the last few months. Unfortunately, it looks like the lion’s share of the increase is due to spam (99% of which gets successfully quarantined).
That is all.
Yea, spam sucks. Greylisting does wonders for it though (especially along with a good filter setup). If you want to see some interesting spam vs traffic graphs you can visit http://mailnoc.its.bethel.edu/
