This option is useful if you don't want to set up MTA on your instance but you have an account at an email provider. ```ini [mailer] ENABLED = true FROM = forgejo@example.com PROTOCOL = smtps SMTP_ADDR = mail.example.com SMTP_PORT = 587 USER = forgejo@example.com PASSWD = mysecurepassword ``` Restart Forgejo for the configuration changes to take effect. To send a test email to validate the settings, go to Forgejo > Site Administration > Configuration > SMTP Mailer Configuration. For the full list of options check the [Config Cheat Sheet](../config-cheat-sheet/#mailer-mailer). > **NOTE:** authentication is only supported when the SMTP server communication is encrypted with TLS or `HOST=localhost`. This is due to protections imposed by the Go internal libraries against STRIPTLS attacks. TLS encryption can be through: - STARTTLS (also known as Opportunistic TLS) via port 587. Initial connection is done over cleartext, but then be upgraded over TLS if the server supports it. - SMTPS connection (SMTP over TLS) via the default port 465. Connection to the server use TLS from the beginning. - Forced SMTPS connection with `IS_TLS_ENABLED=true`. Both `SMTPS` and `STARTTLS` combined with `IS_TLS_ENABLED=true` are known as Implicit TLS and is recommended by [RFC8314](https://tools.ietf.org/html/rfc8314#section-3) since 2018. ## Using Sendmail Use `sendmail` command as mailer. > **NOTE:** For Internet-facing sites consult the documentation of your MTA for instructions to send emails over TLS. Also set up SPF, DMARC, and DKIM DNS records to make emails sent be accepted as legitimate by various email providers. ```ini [mailer] ENABLED = true FROM = forgejo@example.com PROTOCOL = sendmail SENDMAIL_PATH = /usr/sbin/sendmail SENDMAIL_ARGS = "--" ; most "sendmail" programs take options, "--" will prevent an email address being interpreted as an option. ```
