How can I best secure listmailpro?

[thingsdonenow]

The permissions on Unix are kind of lax. Files are readable but not writable.  

 From what I can tell, I'm completely dependent on my web server's security to secure listmailpro and render it unreadable.  

Can I delete config.php, so that the SQL password isn't available?  

Anything else I can do to secure this?

Thanks.

As with most, if not all, PHP / MYSQL scripts your MySQL access info in config.php must be readable.  It is up to the web host to secure your home directory.
