To configure outbound email for user registrations, follow these steps:

  • Log in to the application as an administrator.

  • Select the “Config” menu item.

  • Select the “General Settings” sub-menu and enter the email address that should appear on email messages in the “Gallery administrator email” field. For example, to configure a Gmail account, you would enter your Google Apps or Gmail email account in full.

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.
