+title: 'Mail Forwarding | GMAIL SMTP'
+---
+
+[GMAIL SMTP (Simple Message Transport Protocol)][gmail-smtp] provides a simple way for cloud based applications to send and receive email.
+
+!!! example "Configuration via ENV"
+
+    [Configure a relay host in DMS][docs::relay] to forward all your mail through GMAIL SMTP:
+
+    - `RELAY_HOST` should match your [SMTP Server Endpoint][gmail-smtp::relay-host].
+    - `RELAY_PORT` should be set to [one of the supported Gmail SMTP ports][gmail-smtp::relay-port] (_eg: 587 for STARTTLS_).
+    - `RELAY_USER` and `RELAY_PASSWORD` should be set to your [Gmail Account ID][gmail-smtp::account-id].
+
+    ```env
+    RELAY_HOST=smtp.gmail.com
+    RELAY_PORT=587
+    # Alternative to RELAY_HOST + RELAY_PORT which is compatible with LDAP:
+    DEFAULT_RELAY_HOST=[smtp.gmail.com]:587
+
+    RELAY_USER=someone@gmail.com
+    RELAY_PASSWORD=xxx
+    ```
+
+!!! warning "Process of providing RELAY_PASSWORD"
+
+    You should use your [2-step verification app password][gmail-smtp::2-step-password], **not** your gmail account password.
+    `setup relay add-auth` is a better alternative, which manages the credentials via a config file.
+    
+!!! tip
+
+    If you have set up GMAIL SMTP, you can Filter messages for spam and viruses before they reach external recipients
+    and also apply email security and advanced Gmail settings to outgoing messages.
+
+!!! note "Verify the relay host is configured correctly"
+
+    To verify proper operation, send an email to some external account of yours and inspect the mail headers.
+    You will also see the connection to GMAIL SMTP in the mail logs:
+
+    ```log
