My mail system on my server has never worked at all. No websites can send information to the address on a contact form, sign-up form, etc. No site. I used to be able to at least log in to squirrelmail (even though it has never worked either). Now I get a new error message. Haven't touched or changed any file or folder at all. Here is the new one: ERROR: Config file "config/config.php" not found. You need to configure SquirrelMail before you can use it.
