Configure SMTP for outbound emails
The Bitnami WebMail Pro PHP Stack can be configured to send outbound email through a third-party SMTP server. To configure this, select the domain to be configured in the “AdminPanel -> Domains” section and enter the server name, port and SMTP authentication credentials in the “Outgoing mail” section.
The image below illustrates the process of configuring Gmail for outbound email delivery for a domain:
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.
