This is been happening for about a month now. One of my users sends a message to multiple users. Some users get the message, some don’t. I’ve tracked these messages using the message tracker and on the ones that don’t reach the recipients I get something like this:
SMTP: Store Driver: Message Submitted from Store
SMTP: Message Submitted to Advanced Queuing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
I see no errors in the application log and I can’t seem to find any information anywhere. This happens randomly but always happens when the same users are involved. I’m running Exchange 2000 on a Win2K server, bot with the latest SP. I also have a SurfControl Spam Filter but I don’t have any rules set up to block messages between these users and I’ve checked the logs and these messages are not being caught as SPAM. Any help would be appreciated.
