I thought about doing the /32 as well. I use access list for sendmail, but I was simply entering in the IPs in an excel sheet and using the pull down feature to create the rest of the corresponding IPs. (ie: 1-127 for half a class C). Then import into access file. How are you implementing your list?
I may just have to /32 each and say screw it. :) No aol blocking as of yet. I'm wondering if my ISP has segmented the DSL pools for business and residential. That would be nice as Businesses could be left unblocked. I'm going to call my ISP and try to get more info today. > -----Original Message----- > From: Rick Macdougall [mailto:[EMAIL PROTECTED] > Sent: Tuesday, July 15, 2003 11:37 AM > To: Chris Santerre > Cc: Spamassassin-Talk (E-mail) > Subject: Re: [SAtalk] (OT) DSL/DIALUP manual BL Catch 22 > > > Hi, > > My list does exactly that... but...
