Several years ago, I found a lot of 10053 errors on our server were attributable to Imail's archaic core code binding it to all IP's. Packet sniffs showed many timeouts were caused when Imail inanely began responding to traffic on the wrong interface!
The issue was drastically reduced when we started using only 1 NIC and 1 IP address. That was my experience with Imail 5-7. Your mileage may vary. :-D Dev Wednesday, June 8, 2005, 10:50:50 PM, you wrote: MG> Can you see this connection timeouts and 10053 MG> errors around the clock and MG> to many different servers or only to certain MG> remote servers?
