The "no host found" makes it sound like it could possibly be a DNS lookup error. Just double-check that you can make DNS lookups from that machine. And in addition to ISPs filtering outbound port 25 for all connections other than their own mail server, some ISPs additionally require SMTP AUTH in order to send email -- and that's getting to be more common. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Nov 3 - Open Source Hardware: Bugs, Beagles and Beyond Dec 1 - IBM's Open Client Deployment Jan 5 - Building a Comunity Site with Drupal
