Hello, Our production environment has been running Squirrelmail 1.4.19, vpopmail, Courier IMAP, PHP 5.2.9 on RHEL 5 without any issues. We are running this on two servers behind a cisco CSS load balancer and both with a /home/vpopmail NFS mount to a common shared storage so that there is only one common set of Maildirs and one common location for vpopmaiI. Squirrelmail is installed to /usr/local/apache2/htdocs/webmail. Here are the pertinent config settings: General Options 1. Data Directory : /var/local/squirrelmail/data/ (sym linked to /home/vpopmail/webmail/data/) # ls -l /var/local/squirrelmail/data lrwxrwxrwx 1 root root 28 Jun 23 11:15 /var/local/squirrelmail/data -> /home/vpopmail/webmail/data/ # ls -l /var/local/squirrelmail/data/default_* -rw------- 1 daemon daemon 23607 Sep 4 13:43 /var/local/squirrelmail/data/default_abook -rw-rw---- 1 daemon daemon 666 Aug 14 09:10 /var/local/squirrelmail/data/default_pref Install Process: 1. Renamed the Squirrelmail root web directory from webmail to webmail-1.4.19 2. Untarred Squirrelmail 1.4.20-RC2 and named it webmail 3. Ran conf.pl from webmail/config and webmail-1.4.19/config in two separate windows ensuring all of the entries are set the same. Error: 1. When logging in as user X, I receive the following error: Error opening ../data/default_pref Could not create initial preference file! /var/local/squirrelmail/data/ should be writable by user daemon Please contact your system administrator and report this error. You can see above that the default_pref file is owned by daemon:daemon with rw perms on both owner and group I then tried to change the config to point directly to /home/vpopmail/webmail/data/ and received the same error with the new location identified. I then removed the symbolic link and placed the default and user X pref's and abook files in /var/local/squirrelmail/data and was able to login successfully. I don't like this because then the files will get out of sync between the two servers behind the load balancer. I found the ".." in the error to be somewhat interesting. Thank you for your support !
