Starting from Magento 1.9 the order confirmation emails are not sent during checkout anymore, instead they are sent with the Cron. To verify this works properly:

make sure your system Cron is up and running (you can check the Cron logs: /var/log/cron to verify that).

make sure Magento Cron is setup correctly and is running every some minutes. You should see something like this in the Crontab of your system:

*/5 * * * * /public_html/cron.sh

This schedules a task to run cron.sh every five minute. (More reading)

There are good extensions like AOE Scheduler in Magento that help you to monitor and manage Cron jobs.
