The c: drive ran out of space ealier today which cause us some email issues. Once I freed up space, email starting flowing again, but at a slower rate. I am looking at the queue in system administrator and see email in the "messages pending submission" folder. I have never seen that before. The other thing that I see is the transaction logs are starting to mount up. I am getting a new log every minute. I have checked the event view and not seeing any errors. I have plenty of space on the c drive, so I am not sure what is going on. Can anyone help??
