I installed SBS2000 about 2 months ago and everything went fine.
About two weeks ago I started getting Delay notifications for a couple of messages now and again. Then I got Undeliverable messages for a few mails. As time has gone on, what started as one or two emails not being delivered is now ALL emails not being delivered.
I can recieve them just fine - I can't send them.
I am completely new to Exchange and do not know what the problem is.
If anyone does, can you please help.
Thankyou.

A good part of troubleshooting and getting advice from your peers is knowing what to include in your posts.

Important information in your case would be:

A) a dump of the error messages from the NDR's (non delivery responses)

B) any eventvwrerrors that pop up continuously in application and system log

There is where you usually start.. a possible cause is pinpointed and the resolution process begins.

Thanks for the comments - here is further information...

I first gat a 'Delayed' message with a status of 4.4.7
Then I eventually get an 'undeliverable' message - Could not deliver the message in the time limit specified. Please retry or contact your administrator.
Again, the number is 4.4.7
I have checked these out on the microsoft exchange website but even though it's telling me what these errors mean, I can't seem to get past them.
I hope that helps further :)
