Installed Exim on Debian - cannot send test @ command line

Hey, I'm using Debian 7.3 and a normal LAMP stack. Just installed Debian per the Linode document, and when I try and send a test message from the command line, it fails with the following:

root@dallas:~# echo "you're an idiot." | mail -s Howdy test@theater11.com

2014-02-08 23:26:04 1WCMu4-0004bE-JN Cannot open main log file "/var/log/exim4/mainlog": Permission denied: euid=101 egid=103

2014-02-08 23:26:04 1WCMu4-0004bE-JN Failed to create spool file /var/spool/exim4/input//1WCMu4-0004bE-JN-D: Permission denied

exim: could not open panic log - aborting: see message(s) above

Can't send mail: sendmail process failed with error code 1

If anyone has any ideas that would rock. I tried changing the permissions on var/spool/exim/input to 777 but that didn't help.

Thanks anyone!
