Bug 198306

Description of problem:

An update to 1.4.7-2 brings a new file /etc/squirrelmail/config_local.php
Only that file looks like follows:

<?php
.....
?>
$default_folder_prefix          = '';

Logging to squirrelmail with such configuration immediately produces:

Warning: session_start(): Cannot send session cache limiter - headers already
sent (output started at /etc/squirrelmail/config_local.php:19) in
/usr/share/squirrelmail/functions/global.php on line 374

Warning: Cannot modify header information - headers already sent by (output
started at /etc/squirrelmail/config_local.php:19) in
/usr/share/squirrelmail/functions/i18n.php on line 335

Warning: Cannot modify header information - headers already sent by (output

Warning: Cannot modify header information - headers already sent by (output
started at /etc/squirrelmail/config_local.php:19) in
/usr/share/squirrelmail/src/login.php on line 53

and much more of the same if you will try to continue, making the whole
thing really unusable.

With a configuration which is not sending warning to a screen
this is a bit better but not much.  "$default_folder_prefix = '';"
gets printed on a screen and this is enough to kill a mail display.

Switching the last two lines in /etc/squirrelmail/config_local.php
fixes that immediately.

Users can obviously edit that file, if they figure out what is
going on, and this is config so  maybe even it will not clobbered
on subsequent updates.  OTOH if this file ends gets included this
makes web server quite unhappy.
