Configure SMTP for outbound emails

Follow these steps:

  • Navigate to the OSClass admin interface.

  • Select the “Settings -> Mail Server” menu item.

  • Configure SMTP as shown below, assuming a Gmail account:

    • Server type: Gmail Server
    • Hostname:
    • Mail from:
    • Server port: 465
    • Username:
    • Password: PASSWORD
    • Encryption: ssl
    • SMTP: SMTP Authentication enables

    Replace the above values with settings specific to your SMTP server. If using Gmail, replace the USERNAME and PASSWORD placeholders with correct values for your Gmail account.

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, your application’s attempts to send outgoing emails may be blocked by Gmail if it considers the authentication attempts to be suspicious. When this happens, you will receive a Gmail security alert at the corresponding Gmail address. To proceed, you will need to manually confirm the validity of the authentication attempt before Gmail will permit the application to send outbound emails. For more information on this and other Gmail issues related to outbound email from your application, refer to our Gmail SMTP troubleshooting page.
