I am out of town at the moment and a client reported the inability to send email and that their internet connection is crawling. I know that the issue has to do with the SMTP service because if we stop it everything returns to normal. This server is not used to relay email for users outside the domain. It is not configured for open relay or anything like that. I have enabled logging and will see what it gleans but because in order to have a stable remote connection that I need to troubleshoot this issue I have to disable the smtp service which does not allow me to access the smtp virtual server queue or see what's being logged in real time. I posted here in case anyone has run across this that could give me some ideas of things to try and to be more proactive. Any feedback is appreciated.
