I have checked if the server configuration is correct using php script the server is able to send email.
cron AOE scheduler is installed and it does not show any errors.
Generate Schedules Every 15 Schedule Ahead for 20 Missed if Not Run Within 15 History Cleanup Every 10 Success History Lifetime 60 Failure History Lifetime 600 Mark job as failed after 15
cron job in cpanel set for every 5 min php -f /home/username/public_html/cron.php
