Say, didn't I answer a similar question a week ago? Hm. Looks like you responded but I never saw the response. http://lists.freebsd.org/pipermail/freebsd-questions/2010-August/220263.html Looking at that tcpdump output, it looks like qmail accepted the connection then immediately dropped it. You'll have to look at your qmail logs to find out why. If it's not generating logs, try running truss or ktrace on the listening process to see if it's crashing on you before it has a change to log anything. -- Dan Nelson dnelson@allantgroup.com
