I need a solution
Hi,
One of my clients who's on premise exchange server is receiving Error: "421 Service Temporarily Unavailable" bounce backs when sending to multiple domain which have messagelabs.com filtering services.
I have emailed investigation@review.symantec.com with example bounce and message and listed domains affected. This was on the 20th July and I have had no response....
Is the IP address 203.122.243.50 listed on any of your internal list's as I can't find it listed anywhere on any blacklists.
Thanks
