Rocket.Chat have multiple features using email, like notifications, email verification, mailer, and much more.
Before using those features, you will have to connect a SMTP server to Rocket.Chat. To do that you will need to have access to an SMTP server and valid SMTP login credentials.
Go to Administration settings -> Email -> SMTP.
- Your SMTP server’s host name (e.g.
- The port (usually 587 for modern, secured SMTP servers)
- Your credentials
- A name and email to appear in the “From” field of the emails
Once filled, click “Save changes”.
Go back into the SMTP settings and click “Test SMTP settings”. You should receive an email within a few minutes. If you do not, check the logs (“Administration -> View Logs”) to see what went wrong. NB You might need to make sure Debug logging is on (default is to log Information only).
