I have a new box 3 monthes old, installed imail on it and it would lock up everytime I direct mail ports to it, maybe there is a problem with Imail and P4 systems. I have not migrated to the new system yet. It has been running web(IIS) with no problems. Still running imail on a P3 700. I know that oracle client 8.1X had installer problems on P4 systems. Just my 2 cents worth.

We had a similar configuration - dual 2.4GHz Xeon with 2.5GB RAM running Windows Server 2003, IMail 8.03, 3000+ virtual hosts. Originally we had IMail running on a dual Pentium 3000+ III 933MHz with 1GB RAM and the OS was Windows 2000 Server. We moved IMail to this server in hopes of solving a few problems: 1) The server simply crashes every so often (by "crash" I mean it becomes completely unresponsive). The only recourse being a cold reboot. We have found no clues as to the cause of these crashes. 2) SMTPD32 seems to get bogged down when too much email is coming in (between 50,000 and 100,000 messages a day usually means at least one or two crashes). After moving to this new, more powerful server we had HUGE problems. When I opened the IMail Administrator it would take hours (yes, I said hours) to load the entire tree view of the virtual hosts. SMTPD slowed down to a crawl. It would take so long just to process a single incoming message that SMTPD became unavailable to almost all incoming mail while it tried to proceess the few that it had already received. Ipswitch tech support acknowledged a problem with the way IMail reads the user database from the Windows registry. They said it was a problem with Windows 2003 Server and that there was nothing they could do about it. Too bad they don't mention anything about this on their website where they say that IMail is supported on Window 2003 Server. Needless to say, we rolled back to the old configuration and did our best to deal with the enormous backlog of mail that resulted from this disaster. We are still experiencing the frequent crashes but at least it is better than not receiving mail at all! Unlike you however, the one thing that we don't seem to have a problem with is WebMail. Go figure! I am now waiting for one of Ipswitch's tech support reps to take a hands-on look at our server. I'm sorry if this little story doesn't help with your situation. I think it is relevant though. Anyone who is hosting a large number of virtual mail hosts as we are should be aware that there is a serious problem with IMail running on Windows 2003 Server.

I do agree with Rick that ipswitch seems to have ignored this issue. What makes it look very bad is that my server is a dual Xeon 2.4 Ghz with 1 GB of ram, and yet webmail sucks. I believe the flaw exists in the webmail software itself, it just isn't written well. I will often see the service consuming 70% of the cpu's, and it was just started, hardly any users on it. To top it off, we've noticed that imail's other services (smtp, queue manager, pop, etc) are cpu hogs as well. We have about 5000 domains on imail, and it had been running fine without incident on a single 1.4 Ghz cpu machine for a long time, then we upgraded to 7.3 then to 8 and 8.3 and since then the performance of the services has hit rock bottom, forcing the server change to the dual xeon's. We have made many calls to ipswitch over the past week, and they continue to attribute it to things that don't make sense, they seem to be making up excuses for it and can't resolve the core issue. We have found out very quickly that ipswitch has become irrelevant, unable, and unwilling to provide quality support. We are looking into migrating to other mail server software.
