[imp] question about E-mail slow showing in IMP

[alex]

To one who may concern,

I am now using CentOS4 with imp-h3-4.1.4-1.el4.centos and courier-imap After
User A login to webmail, it is very slow to show the first 20 message header
of each folder.
I have checked the httpd log, horde log and php log is no strange things
related.
If I am using User B login, with symbolic link to user A's "Maildir", it
works fine with normal speed!
