Using Swift Mailer and I'm getting this error?

Warning: is_writable() [function.is-writable]: open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (VIRTUAL_DOCUMENT_R开发者_如何学编程OOT) in /www/zxq.net/g/t/a/gtag/htdocs/lib/preferences.php on line 15 blarg!

This is what is on Line 15 of preferences.php: if (function_exists('sys_get_temp_dir') && is_writable(sys_get_temp_dir()))

Any clue what this means? Thanks

SiftMailer wants to write a file to the system's temporary directory, which is /tmp.

Your host has restricted you from being able to write files outside certain directories. You're not allowed to write a file to /tmp.

This warning has informed you of these facts. It means what it says!
