Windows NT E-mail Problem

[dennco4]

We currently have a server running Windows NT and have the postoffice installed on to it for our internal e-mails. We had it on a different server but that one crashed and we had to reinstall the postoffice and setup a new one for all of our users. Since we have done that we have being running into a few problems. One of them is that somtimes when a user sends an internal e-mail it will be bounced back to them with an undeliverable message attached. Can anyone tell me what might be causing this? We have tried restarting the server and that didn't seem to help. We think it might be memmory issue but we have ran the performance monitor and show no real changes in the memory. Let me know if you need anymore information. Thanks for your help in advance.

Thanks,
Dennco

Are the e-mails that are being sent back being sent to the same person? Can you get into the Postoffice to administer it?
