We are having a problem with outbound email not being sent. We have a Microsoft 2003 SBS with SP2 and Exchange 2003. I have loaded all OS and Exchange updates that I find. Still doesn't want to send out emails until I either reboot the server or unload the SMTP service. When I try you unload the SMTP service, it take forever and eventually will give an error about the service being unresponsive but it looks as if the service did stop. The logs don't appear to point to anything. Virus scan is clean. I'm in desperate need of assistance as this has been going on for weeks and I'm about ready to pitch the Exchange Server out the windows and go with an outside email provider. Any help would be appreciated.
