For the last 4 hours we have had a issue with our external and internal email which is not being delivered.
When we look at the tracking for all the messages sent the message ends by being submitted to the categorizor and goes no further. Our awaiting directory lookup folder is now in excess of 500.
Wew are running exchange 2003 with Trend micro. We have tried a few solutions found on the web but no luck yet.
Any help apreicated.
