It could run ok, could run not so ok. The pb's will be in the list maintenance (subscribe/unsubscribe and bounce) plus the Imail list server can be unaggressive in delivering list traffic although 6.06 is supposed to have made some improvement in the SMTP client area (the process that sends mail). So if the lists are discussion lists, the turnaround time can be variable to long. Throw in your spam/relay pb's, and you could have fun. >Win 2000 - SP1 >PIII 750 >768mb RAM That's certainly plenty of box for a mail server. Since you are on this list, I assume your users are (heavy) users of web mail. If the 8K list is a discussion list, then just 10 or 20 list msgs/day will generate 80K or 160K messages. Do you have any idea of what your traffic is now? I suggest you try it and see how it goes. But everybody knows Imail's list server is very basic, so be ready to seek relief quickly. Msg deliveries can be offloaded to IMGate, which will also fix your relay/spam pb's. Then if list maintenance/stability is a pb, then I'd recommend using a real list server such as Listar + postfix on FreeBSD on a separate machine of not necessarily such power. The software is free but magnitudes better than Imail list server. I have client running announcement lists of 20k members and getting 40K msg deliveries/hour. Many people run list of 70K and above on Listar.
