We have a small network in our offcie. With a Server running Windows 2003 server and Exchange 2003.
All users were able to send and receive internal mail to each other, but for some unkown reason this has stopped working and all internal mail end up in the Bad Mail folder.
I have stopped the SMTP server but as I expected it did not solve the problem.
We do not have a mail server and indivdual users all have their own emails and directly send and receive emails via a dsl router. The emails to external addresses are not effected by this fault, as we only use the exchange for sharing public folders and internal mail.
Any help would be appreciated
