I upgrade from 5.012 to 6.51 last week without any problem. Today, some users ask for a problem in router, because they are trying to sent msgs and any msgs arrived in any mailbox (they are correct, there is a problem). I checked the server console when I sent a msg to see the log of it, but nothing appears and any msg was delivered… I try to restart the router, but didn´t worked, I was force to shutdown the server to fix the problem.
Anyone can help me ?
