[dba-Tech] Spam ceased?

Hi all

This is so strange.  Until recently about 83% of all mail received here was
spam. Suddenly the hammering spambots seems to have ceased sending spam
leaving only the yahoo, gmail, and Hotmail types (lottery and so on)
manually operated accounts. Our spamfilter can stay quiet for 15 minutes or
more, a situation I can't recall to have seen in modern time.

Anyone else seeing this?
