A rogue application may be periodically fighting Imail for the outgoing smtp port, or you may have a shady NIC. During this period of outage, are you able to telnet your local IP and if so, what answers?

Our mail server (8.22) will not send emails. It will receive the emails (we use Declude) scan it then put it in the spool folder. When you look in the log files you see entries where it could not connect to other mail servers and if you try to telnet to other mail servers its not working. No reports of any problems when we check the event viewer. We put a rule for all outgoing traffic in the firewall but could not see any entries at all, neither good or bad. Doing a netstat we see tons of TIME_WAIT when its not working. Rebooting the firewall did not fix it but rebooting the server did. Stopping and starting either Quemanager or SMTP did not fix it either. It appears like SMTP is being blocked by the server itself (no security software active or installed), either by a large amount of connection in TIME_WAIT or something else. Not sure where to look next so all suggestions will help.
