Frank, it looks like you're correct. I happened to be reading today an article called "Pernicious Ports" http://www.berghel.net/col-edit/digital_village/dec-05/dv_12-05.php =========================================================================================================================================================== (2) Unix-Centric Most UNIX systems, regardless of brand, offer SMTP mail services through TCP port 25. If the system is not actually a mail relay or server, then you likely do not need this service running at all. The main exposure lies in the failure to continuously patch the system. By the way, it is a common misconception that an SMTP server must be running for a local user or service to send email out of a UNIX box. This is simply not true. The recommended solution is to block TCP 25 at the firewall. ============================================================================================================================================================== Could someone possibly explain how email works without an SMTP server and/or how the "common misconception" arose? _______________________________________________ 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
