3128 is the default Squid port. What do the ACL's on your Squid server look like? If it's wide open, it will definitely find its way into the CBL, as open proxies can be very quickly subverted to send spam. If your machine forwards outbound connections to port 25 (as a NAT/MASQ router for instance), and if there is any host behind it infected with some kind of spam-generating malware (very common, if you have any Windows boxes), that will very quickly put you on CBL. This happened to our GNU/Linux-based router once; I had to disable forwarding of port 25 (so now the only way to send mail would be to use the official mail server) to get it delisted. -- What this country needs is more unemployed politicians. http://stormwyrm.blogspot.com/ _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
