Hello, Currently my email server (600Mhz p3) is having some trouble with mail boxes with more than 1000mails (each one is < 5kb). RegularIMAP access through a client (ex mutt, endura, outlook) is fast. telnetting to the server and doing SELECT INBOX is also relativelyfast, taking about .5 seconds. However, logging into the account on squirrelmail takes about 30 seconds for a page to load which is not very productive. The user has about 30 mailboxes into which he (manually) distributes the mail from the inbox. Perhaps the large number of folders could be bogging down the server? I notice uw-imapd cpu usage near 100% when the user is logging in.I know the server is a bit on the slow side but are there any tweaks? Perhaps switching to Maildir and using courier-imap?Thanks.

I'm running an Epia VIA 533 for my mail server and have seen the same problems.
Mozilla and Firefox will load a imap directory in a few seconds. However I believe they cache locally. But for folders that are new to the client, no cache, they load up nicely.
perls Mail::IMAPClient can pull in 2000+ in a few seconds (IIRC 4) on an application I'm writing.
Squirrelmail takes a very long time and frequently failes when things get much above 1,000 for me as well.. IIRC it's memory size errors in most cases. However, there are times when it just doesn't respond.
I don't think it's the number of folders as each one is worked on seperately by IMAP protocol. I do think it's squirrelmail. It's having trouble when you get to 1,000+ emails and I can't tell you if it's a machine, php, squirrelmail, or configuration issue. Considering how well other applications can manage the IMAP connection I'm inclined to think the IMAP server is just fine.
