Probably not. Every year around the holidays our spam hits a yearly low usually the week of Christmas, then goes right back up to the previous levels. I think some of the spammers may be taking a holiday break as well.
I have to agree, but only based on my experiences this year. We had incredibly low mail volumes (mailing lists included) throughout the holiday period, then yesterday we had one of our biggest spam days ever.
Of course, since we're using SA (and dropping high scoring messages), I got only 1 spam in my mail, and it was properly marked as such ;-).
