To use Gitea’s built-in Email support, update the
app.ini config file [mailer] section:
Use the operating system’s sendmail command instead of SMTP. This is common on Linux servers.
Note: For use in the official Gitea Docker image, please configure with the SMTP version.
[mailer] ENABLED = true FROM = email@example.com MAILER_TYPE = sendmail SENDMAIL_PATH = /usr/sbin/sendmail
[mailer] ENABLED = true FROM = firstname.lastname@example.org MAILER_TYPE = smtp HOST = mail.mydomain.com:587 IS_TLS_ENABLED = true USER = email@example.com PASSWD = `password`
Restart Gitea for the configuration changes to take effect.
To send a test email to validate the settings, go to Gitea > Site Administration > Configuration > SMTP Mailer Configuration.
For the full list of options check the Config Cheat Sheet
- Please note: authentication is only supported when the SMTP server communication is encrypted with TLS or
HOST=localhost. TLS encryption can be through:
- Via the server supporting TLS through STARTTLS - usually provided on port 587. (Also known as Opportunistic TLS.)
- SMTPS connection (SMTP over transport layer security) via the default port 465.
- Forced SMTPS connection with
IS_TLS_ENABLED=true. (These are both known as Implicit TLS.)
- This is due to protections imposed by the Go internal libraries against STRIPTLS attacks.
The following configuration should work with GMail’s SMTP server:
[mailer] ENABLED = true HOST = smtp.gmail.com:465 FROM = firstname.lastname@example.org USER = email@example.com PASSWD = *** MAILER_TYPE = smtp IS_TLS_ENABLED = true HELO_HOSTNAME = example.com
