Search the archives for the registry tweaks for TCP TimedWaitDelay and other tweaks that will make Imail close some connections quicker under heavy load and have more available ports to dynamically assign. I have a .reg file that I run on all of our mail servers now before installing Imail or any other mail server software.

There are actually multiple issues but I believe all come from one source. Lots of times upon sending to certain domains, our mail server will pause between the sending of the data, to sending the . to indicate that the e-mail has completed (sometimes up to 15 minutes). This in turn causes the remote server to sever the connection. IMail thinks that the msg never got sent and re queues it. However every time this happens, the remote user receives duplicate copies up until I delete the msg from the queue or it reaches the maximum and returns back to the sender as undeliverable. The 2nd issue is lots of timeouts upon checking IMAP and POP mailboxes. This happens more often if there are a large number of messages to download or synch. The error received here is 10053. On other similar winsock errors, people were told to change NIC settings, or just buy a better one... The one we have is a "3Com Gigabit Ethernet Server NIC (SX/TX)". So far I've dropped it down to full duplex 100mb/s and turned the jumbo MTU frames on and set to 1500. Are there any other settings I might change? I might try another built in NIC that the server has tonight just to see if that makes things any better. Thanks!
