We recently had to rebuild our exchange server and perform the exchange /disaster recovery option in order to get the exchange to install. Everything was fine for a couple days and now the server hangs up and we have to reboot in order to get email to flow again. I'm noticing a hugh amount of email in queue not going anyway. I'm thinking that the server hangs after the queque gets so full. Any ideas? There isn't any errors in the event logs. No virus protection at this time because I haven't had time to reinstall. Windows 2003, and exchange 2003 standard. Image of the queue attached.
