Another problem I found in the process of running the mail import
is that the script has need of permissions to write to a logging
file. If the file does not exist then the permissions acquired
running the maillist.php will try to create the /var/www/FUDforum/errors/sql_errors file. If these permissions conflict with
the permissions of the account running FUDforum then the
forum code gets errors and cannot read it's own log file.

Also when the file is removed and recreated any previous permissions granted to these files are also removed.

As such, all necessary log files should always be in place even
if they contain no data.

Below is the output from procmail that contains the error that I am referencing.
------------------------------------------------------------------
procmail: Executing "/var/www/FUDforum/scripts/maillist.php,2"
PHP Warning: pg_query(): Query failed: ERROR: value too long for type character varying(100) in /var/www/FUDforum/include/theme/default/db.inc on line 93

It makes sense. Can you prepare a fix for us?

I will try. After making the /var/www/FUDforum/errors/sql_errors file with the correct permissions, I got only one message through
before I get the same error again.

Now I'm stumped.

Also there really should be some isolation. The maillist.php
imports all the of the web interface, themes, etc. It really
should only need the permissions and database schema to insert
into the proper forum.

I'm trying to figure out why the error is occurring in the first place.

It may help to disable safe_mode in php.ini. It causes a lot of strange behaviours and will eventually be removed from PHP anyway.

If all else fails, you can create an intermediate root script (script A) to copy messages and chown them. Script B can then import them with the forum's user.
