When the problem occurs and I run a netstat -an it does NOT show Active Connections
Proto Local Address Foreign Address State TCP 0.0.0.0:25 0.0.0.0:0 LISTENING So I am assuming what you had said about showing possible SMTP/SMTPD thread saturation, meaning no more listening (SMTPD) or delivery (SMTP) threads available is what is occuring. What can I do to correct this? I am using a good kill file, I have all of the spam filters correct, I have relay for local addresses enabled, I have check to ensure no virus or other program is running. The resource usage on all processes are low, and I am running no other services on this machine at this time. I have read the ipswitch article http://support.ipswitch.com/kb/IM-19980302-ES01.htm and am under the assumption this would possibly correct this but I am not forsure. Can anyone help shed more light on this form me.
