I don't think AT&T cares, since I complained about a massive snowshoe spamming campaign a couple of months ago--no action taken it seems--and they have netblocks all over the place there. A bunch of customers were calling me since their junk was being scored low by spamassassin and ending up in inboxes. Blah! I've seen spam from each one of their blocks at at&t. 99.155.208-209 99.51.80-81 99.170.198-199 99.16.32-39 On Tue, Nov 03, 2009 at 08:32:10AM -0800, Michael Peddemors wrote:
