You can do this with postfix using the reject_rbl_client directive. I believe some or all of them allow you to download/rsync lists, too. While I picked ones specifically for spam, as I recall they offer various lists, some by country, etc., which may be of use to you.</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">Some are lists of just dynamic DNS ranges, like IPs assigned to home internet connections. That's appropriate for blocking email, but not other IP, like ssh or vpn connections. I got those from dnsstuff.com. I used to be a paid member there, but while I like the service I didn't use it enough to justify the ever increasing fees. Still, you might find some other useful info there.</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">Scott<br></font><br><hr id="zwchr" style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt;"><div style="color: rgb(0, 0, 0); font-family: Helvetica, Arial, sans-serif; font-size: 12pt; font-weight: normal; font-style: normal; text-decoration: initial;"><b>From: </b>"Michael B.
