Active Connections
Proto Local Address Foreign Address State TCP 0.0.0.0:25 0.0.0.0:0 LISTENING
in the above case, also telnet to that ip port 25 and see if Imail picks up the phone, or timeout, or connection refused.
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?
If the SMTPD is really overwhelmed with "too many" simultaneous connections ( I can produce this at will with IMGate as the MX), then the problem may be that SMTPD is having trouble dumpting the inbound msgs on the queue, the disk is really the problem, not STMPD.
I am using a good kill file, I have all of the spam filters correct, I have relay for local addresses enabled
ip addresses, not email addresses, right?
it doesn't take much CPU occupation to saturate the disk access, so when the state occurs, does task manager show a lot of disk i/o?
