    Can't send mail due to excessive connections to port 25

    676833
      I ran lsof and found anywhere between 28-60+ connections for port 25. See below. If I kill the PID, my emails go through. I can send emails internally but outbound, they won't go out unless I reset the connection. I've tried blocking those IPs using iptables but haven't had much luck. Any ideas?
