Errors Like "Notice: Use of undefined constant SORTARRIVAL - assumed 'SORTARRIVAL' in include/imap.inc.php on line 252"

If you get this error (and usually a whole set of them), then your PHP does not have the IMAP module.

In many Linux distributions, install either php-imap, php4-imap, or php5-imap, depending on your distribution. If you built PHP from source, you may need to rebuild it with IMAP support.
