Hi,
  Im stumped! Never seen this before.

I have the following setup. 2 Mailbox's and 2 Cashub's, both clustered. Mails are sent and received via postini. Storage is common (MSA).

It started by slowly where external emails stopped being delivered. then users could not even send internal emails.

As of now, I can only receive external emails. Cannot send internal or external emails. Tried disabling the smarthost (Postini, since we have a static IP) as well. No go.

I have shut down and restarted the storage and all the server's. Same issue.

There is no NDR, nothing in the outbox or the Q's either

Any help would be great.

Thanks

did you check with the mail flow trouble shooter tool from the tools menu Exchange management console?

if the email are not in queue then if you track the mail in message tracking, is those emails handover to postini? if yes check with postini

you mentioned internal emails are also not delivering.. what is the status, when you track the email in message tracking? no emails in the queue viewer?

If you setup outlook in a new profile or on a new PC, does it have the same problem?

Shoudl you close outlook and re-open using
Start>Run>outlook.exe /safe

now try to send an email?
If it works, the issue is going to be with an addin
Will need to find which one it is and disable

Ok, so the issue is resolved. Am posting what happened and the solution for anyone who might reach here because of a similar situation.

The last few patches seem to have cause the issue. Especially since there were some security updates for the .NET 2.0 package.

The Microsoft Exchange Mail Submission service stopped and was getting timed out. So mails were not being sent to the CAS servers.

Simply had to add the entry  <generatePublisherEvidence enabled="false"/> to the config file of the service and everything went back to normal.

Hope this helps someone.

Thanks guys for trying to assist
