The script /includes/class_dm.php is not part of the EI mod but obviously its methods are being used when posting the email messages.

This is primarily to prevent a user from easily spamming members. Set it to 0 to disable this option."

It would be useful to see what actual error causes the $errors array to have a message. Have you tried to change the 30 second limit to 0?
