- Relay Button
- You can specify only the servers that you want to be able to send email here by selecting Only the list below and adding your servers IP addresses.
- Delivery Tab
- Outbound Security Button
- Select Basic Authentication and specify your Gmail account and password. Check the TLS encryption. (If you use other SMTP server, it may not support TLS and cause error)
- Outbound connections button
- Set TCP port to 587 (This is Gmail port, default port should be 25)
- Advanced Button
- specify the smart host as smtp.gmail.com
- Now configure the Outbound email in SharePoint to send email to the server where you have installed this SMTP server.
