This is a simple setup and yet I cannot send a test email. What I did is as following:
1. set up an outgoing mail server
1a. SMTP Server: mydomain.com (yes, this is same as my domain name)
1b. SSL/TLS enabled, Port 465
1c. username and password filled
2. Test connection successfully ("Connection Test Succeeded! Everything seems properly set up!")
3. Alias Domain is set to mydomain.com (Settings->Configuration->General Settings)
4. Going to Settings->Technical->Emails
5. Create a test email to send
6. After I click the "Send Now" button, it states "Delivery Failed".
What is wrong with this set up? It works fine if I use different SMTP server such as gmail but not my own hosting domain SMTP.
Help anybody? Is this a bug? I would like to use my own hosting SMTP server instead of using gmail. My hosting SMTP is working fine with my email client but not Odoo.
