Our application deployed on two LINUX virtual machines in Azure. And the application needs to send emails out in some events in it's work flow.
So, the app using PHP standard mailer (actually it's a combination of YiiMailer, SiwftMailer) and we are trying to use Microsoft O365 email account to relay these emails. So far we didn't able to work this out.
What are the other recommended methods for sending emails out ? without going emails SPAM or JUNK at any cost.
Thanks for your time !
