I'm running IMail in various locations on various platforms with a varying amount of users and volume. All run well and all are running ASSP on the same servers. None of the servers are above 500Mhz machines and most have 512 meg. All are Win2000.
The only thing I've ever had an issue with is using IMAP. When checking sent items at the client it is fairly quick, but when checking the Inbox the headers are shown pretty quickly, but it takes a very long time to download messages, even on a LAN. This happens whether there are 20 messages or only one. As a matter of fact, I have a couple of customers that initially wanted to use IMAP and then asked me to switch them to POP to get away from the long wait times. ----- Original Message ----- From: "Ed Butler (49pence)" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, April 02, 2004 07:28 Subject: [IMail Forum] Imail performance > We're in the process of evaluating Imail for our users.
