comcast abuse/admin?

If anyone from comcast is here, we would like to talk to someone on your end about abuse from your network (mainly inbound spam from a lot of your netblocks to our mail pool.) Basically we would just like to blot out a number of netblocks in your space from our mailservers that just feed us a constant spew of spam, but we welcome dialog from your side to ensure legit email is unimpeded (by telling us where your outbound mailhubs are, etc) -mark -- Mark Jeftovic <markjr@easydns.com> Co-founder, easyDNS Technologies Inc. ph. +1-(416)-535-8672 ext 225 fx. +1-(416)-535-0237
