I have a server that is hosted on a VPS in the Netherlands and have been running SpamAssassin for the past 3 months without any issues. During the past week I have received four cron job errors when I try to update the SA rules. It appears my IP address has been blacklisted as I can't ping pccc.com or sa-update.pccc.com and as a consequence the "GET" command to retrieve the tar file at night fails. Here's the error that I'm getting from the cron job:
etc/cron.daily/spamassassin: http: GET http://www.sa-update.pccc.com/1781032.tar.gz request failed: 500 Can't +connect to www.sa-update.pccc.com:80 (timeout): Can't connect to +www.sa-update.pccc.com:80 (timeout) LWP::Protocol::http::Socket: connect: +timeout at /usr/share/perl5/LWP/Protocol/http.pm line 51.
