I just installed IMP3.0, I can see the login screen, but each time I =
tried to login to the server, an error message appeared "Your Mail =
session has expired. Please login again.". I checked my log file, I =
noticed that it succefully login and logout immediately.

My server setting:
solaris 8,
php 4.1.2
mysql 3.23.43
Courier-IMAP server


Is there any thing I need to notice to overcome this problem?=20
