I am using Magento 18.104.22.168 and have installed SMTP pro module to send email.
When I run smtp self test from admin, it successfully sends email to provided email id.
But on customer signup, order placed and click on send email button from admin, there is no mail sent to customer/guest.
When I load "mydomain.com/cron.php" or set cron setting in cpanel, no mail is sent to customer.
Please tell me the email settings for Magento 22.214.171.124 and what is the problem here?
