A lot of the email people – such as Google, Outlook, Yahoo, and maybe even more – require a configuration for emails now to include the sending domain. Here’s an example of a configuration file from another popular app I use to give you the idea…
smtp_host="smtp.provider.com"
smtp_port="587"
smtp_user="noreply@mydomain.com"
smtp_pass="passwordfortheuser"
smtp_from="My Website <noreply@mydomain.com>"
smtp_domain="mydomain.com"
I have been working with playing around with Mailgun to make this work again. I tried to enable and disable SSL/TLS to `true`. I have tried Outlook, Yahoo, and Google. I am honestly lost on why I am having issues now.... I did read about this.
Also, Mailgun is not saying it is sending or even failing to deliever emails at all. They were working about a month ago when I last invited a staff member.
