Hi all,
I want to use the server_side_filters plugin to do the procmail filter in the server side.
version list:
squirrelmail-webmail-1.4.22
server_settings_backend-2.0-1.4.0.tar.gz
server_side_filters-2.0beta1-1.4.0.tar.gz
compatibility-2.0.16-1.0.tar.gz
And I have enabled the server_side_filters throw config/conf.pl script.
Plugins
Installed Plugins
1. server_side_filters
Available Plugins:
2. administrator
When I use "Options" -> "Message Filters" in my web browser, after add some filter rules, and click the SAVE button, it says "Error: Error deleting file or directory"
And in my /var/log/httpd/ssl_error_log:
PHP Warning: unlink(/): \xca\xc7\xd2\xbb\xb8\xf6\xc4\xbf\xc2\xbc in /var/www/html/webmail/functions/global.php on line 278, referer: https://mymailserver.com/webmail/plugins/server_side_filters/options.php
Here is the global.php function:
275 function sq_call_function_suppress_errors($function, $args=array()) {
276 $display_errors = ini_get('display_errors');
277 ini_set('display_errors', '0');
278 $ret = call_user_func_array($function, $args);
279 ini_set('display_errors', $display_errors);
280 return $ret;
281 }
Anyone can give me some advice?
Thanks,
Bu Xiaobing

Remember to also use %1 instead of %n in NEW_SETTING_TEMPLATE and %1 and %2 instead of %u and %d respectively in FILE as well. A new version of the backend plugin will be out in the medium term where you will need to revert these changes back to what you originally found in the filters plugin examples. -- Paul Lesniewski SquirrelMail Team Please support Open Source Software by donating to SquirrelMail! http://squirrelmail.org/donate_paul_lesniewski.php |

If you don't say *how* -- explain carefully what you changed, what
your current settings are, then you leave us to guess. This is
frustrating and you are less likely to receive any help this way.

The only examples I can find point to the server_settings_backend
directory. The copy of the suid_wrapper in the suid_backend directory
shouldn't be used in your configuration. (I believe this is your
oversight, unless you can point out where there was a misleading
example.)

This is good in general. If you really need directory traversal
(why?), read the docs on how to compile the suid wrapper. And once
again, READ THE DOCS **BEFORE** you ask for help.

Thanks for your help. I read the server_settings_backend/docs/SUID_BACKEND_ERRORS and find the problems and it works now!

Thanks for reading the docs. I'd just caution you again *against*
allowing directory traversal. There is no reason you should need that
and it is less secure.

Do you mean I should not use SUID backend?
For now, I need SUID to save a kickoff file .forward which contains "|exec /usr/bin/procmail || exit 75" at /home/USER, So I can invoke procmail to do filter. And I compiled SUID with --enable-auth=imap to do authentication.

I never said such a thing.

Let the wrapper obtain the user home directory. The SquirrelMail side
(the filters plugin) should only pass the name of the file (.forward)
and no path information.

I changed the server_side_filters_procmail/functions.php as the followings where MAILDIR=$HOME/mail was configured in /etc/procmailrc
161 // determine the right path to the user's mail store
162 //
163 if (empty($custom_mail_location))
164 {
165 $mail_location = NULL;
166 $folder_path_prefix = '$MAILDIR';
167 //$folder_path_prefix = '$DEFAULT';
168 }
169 else
170 {
And now it can works as I want, unfiltered mails will delivered to the DEFAULT=/var/mail/$USER location, and filtered mails will delivered to MAILDIR=$HOME/mail/folder_name.
