Configure SMTP for outbound emails
- Google Cloud Platform doesn’t allow SMTP traffic through default ports: 25, 465, 587. Check Google cloud documentation to learn how to use a VPN to bypass these restrictions or use a different port for sending emails from your application.
To configure outbound email, follow these steps:
- Log in to the application as an administrator.
- Select the “Setup -> E-mails” menu item.
- Click the “Modify” button.
- Select the “SMTP/SMTPS socket library” as the method to send email.
- Enter details for the SMTP server to be used for outbound email. For example, to configure a Gmail account, you could use the settings below. Replace USERNAME and PASSWORD with your Gmail account username and password respectively.
- SMTP/SMTPS Host - smtp.gmail.com
- SMTP/SMTPS Port - 465
- SMTP ID - USERNAME@gmail.com
- SMTP Password - PASSWORD
- Use TLS (SSL) encrypt - Yes
- Sender email - USERNAME@gmail.com
- Click “Save” to save your changes.
Once you have made the above changes, you can use the “Test sending” option on the “Setup -> E-mails” page to send a test email to one or more recipients and verify your outbound email settings.
To configure the application to use other third-party SMTP services for outgoing email, such as SendGrid, refer to the FAQ.
NOTE: If you are using Gmail as the outbound email server and have experienced issues trying to send emails correctly, check the Gmail SMTP troubleshooting page to learn the causes of these issues and how to solve them.
