I am able to send group emails from a search (less than 50), am able to send a test email from the Administer / System Settings / Outbound Email, but when I try to do a CiviMail test, I get Error in call to Mailing_send_test : mail() returned failure.
What should I look for?
I'm running CiviCRM 4.6.4 with Drupal 7.3.8 and here's the contents of the ConfigAndLog file after trying to send mail with the Debug and Backtrace on
