I work on PC support, but am a novice with servers. I have been asked to look at a system which is running Windows 2000 server and will receive emails but will not send. After a day or two the emails are returned as 'unreachable destination'
I have looked in the exchange server and the queue 'messages with an unreachable destination' contains 83 emails, a few of which come from PCs on the server (there are only 2), but the majority appear top come from spam addresses.
Please can anyone help me sort this out.
