# Email setup
|
||
|
||
To use Gitea's built-in Email support, update the `app.ini` config file [mailer] section:
|
||
|
||
## Sendmail version
|
||
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.
|
||
```ini
|
||
[mailer]
|
||
ENABLED = true
|
||
FROM = gitea@mydomain.com
|
||
MAILER_TYPE = sendmail
|
||
SENDMAIL_PATH = /usr/sbin/sendmail
|
||
```
|
||
|
||
## SMTP version
|
||
```ini
|
||
[mailer]
|
||
ENABLED = true
|
||
FROM = gitea@mydomain.com
|
||
MAILER_TYPE = smtp
|
||
HOST = mail.mydomain.com:587
|
||
IS_TLS_ENABLED = true
|
||
USER = gitea@mydomain.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]({{< relref "doc/advanced/config-cheat-sheet.en-us.md" >}})
|
||
|
||
- 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.
|
||
|
||
### Gmail
|
||
|
||
The following configuration should work with GMail's SMTP server:
|
||
|
||
```ini
|
||
[mailer]
|
||
ENABLED = true
|
||
HOST = smtp.gmail.com:465
|
||
FROM = example@gmail.com
|
||
USER = example@gmail.com
|
||
PASSWD = ***
|
||
MAILER_TYPE = smtp
|
||
IS_TLS_ENABLED = true
|
||
HELO_HOSTNAME = example.com
|
||
```
