Security and PostfixAdmin
|
|
-------------------------
|
|
|
|
While the developers of PostfixAdmin believe the software to be
|
|
secure, there is no guarantee that it will continue to do be so
|
|
in the future - especially as new types of exploit are discovered.
|
|
(After all, this software is without warranty!)
|
|
|
|
In the event you do discover a vulnerability in this software,
|
|
please report it to the development mailing list, or contact
|
|
one of the developers directly.
|

DATABASE USER SECURITY
|
|
----------------------
|
|
|
|
You may wish to consider the following :
|
|
|
|
1. Postfix only requires READ access to the database tables.
|
|
2. The virtual vacation support (if used) only needs to WRITE to
|
|
the vacation_notification table (and read alias and vacation).
|
|
3. PostfixAdmin itself needs to be able to READ and WRITE to
|
|
all the tables.
|
|
4. PostfixAdmin's setup.php additionally needs permissions to CREATE
|
|
and ALTER tables in the PostfixAdmin database. For PostgreSQL, also
|
|
permissions for CREATE FUNCTION and CREATE TRIGGER are needed.
|
|
In other words: setup.php needs all permissions on the PostfixAdmin
|
|
database.
|
|
|
|
Using the above, you can improve security by creating separate
|
|
database user accounts for each of the above roles, and limit
|
|
the permissions available to them as appropriate.
|
|
|
|
|
|
FILE SYSTEM SECURITY
|
|
--------------------
|
|
|
|
PostfixAdmin does not require write support on the underlying
|
|
filesystem with the following exceptions:
|
|
- the templates_c directory where Smarty caches the templates
|
|
- PHP's session.save_path to store session files
|
