* `SMTP_PORT`: port for SMTP; defaults to 25 for `smtp`, 465 for `smtps`, and 587 for `smtp+startls`
* `ENABLE_HELO`, `HELO_HOSTNAME`: reverse `DISABLE_HELO` to `ENABLE_HELO`; default to false + system hostname

- `HELO_HOSTNAME`: **\<empty\>**: Custom hostname for HELO operation.
- `HOST`: **\<empty\>**: SMTP mail host address and port (example: smtp.gitea.io:587).
- As per RFC 8314, if supported, Implicit TLS/SMTPS on port 465 is recommended, otherwise opportunistic TLS via STARTTLS on port 587 should be used.
- `IS_TLS_ENABLED` : **false** : Forcibly use TLS to connect even if not on a default SMTPS port.
- Note, if the port ends with `465` Implicit TLS/SMTPS/SMTP over TLS will be used despite this setting.
- Otherwise if `IS_TLS_ENABLED=false` and the server supports `STARTTLS` this will be used. Thus if `STARTTLS` is preferred you should set `IS_TLS_ENABLED=false`.
- `FROM`: **\<empty\>**: Mail from address, RFC 5322. This can be just an email address, or
the "Name" \<email@example.com\> format.
- `ENVELOPE_FROM`: **\<empty\>**: Address set as the From address on the SMTP mail envelope. Set to `<>` to send an empty address.
- `PROTOCOL`: **\<empty\>**: Mail server protocol. One of "smtp", "smtps", "smtp+startls", "smtp+unix", "sendmail", "dummy". _Before 1.18, this was inferred from a combination of `MAILER_TYPE` and `IS_TLS_ENABLED`._
- SMTP family, if your provider does not explicitly say which protocol it uses but does provide a port, you can set SMTP_PORT instead and this will be inferred.
- **sendmail** Use the operating system's `sendmail` command instead of SMTP. This is common on Linux systems.
- **dummy** Send email messages to the log as a testing phase.
- Note that enabling sendmail will ignore all other `mailer` settings except `ENABLED`, `FROM`, `SUBJECT_PREFIX` and `SENDMAIL_PATH`.
- Enabling dummy will ignore all settings except `ENABLED`, `SUBJECT_PREFIX` and `FROM`.
- `SMTP_ADDR`: **\<empty\>**: Mail server address. e.g. smtp.gmail.com. For smtp+unix, this should be a path to a unix socket instead. _Before 1.18, this was combined with `SMTP_PORT` under the name `HOST`._
- `SMTP_PORT`: **\<empty\>**: Mail server port. If no protocol is specified, it will be inferred by this setting. Common ports are listed below. _Before 1.18, this was combined with `SMTP_ADDR` under the name `HOST`._
- 25: insecure SMTP
- 465: SMTP Secure
- 587: StartTLS
- `USE_CLIENT_CERT`: **false**: Use client certificate for TLS/SSL.
- `FORCE_TRUST_SERVER_CERT`: **false**: If set to `true`, completely ignores server certificate validation errors. This option is unsafe. Consider adding the certificate to the system trust store instead.
- `USER`: **\<empty\>**: Username of mailing user (usually the sender's e-mail address).
- `PASSWD`: **\<empty\>**: Password of mailing user. Use \`your password\` for quoting if you use special characters in the password.
- Please note: authentication is only supported when the SMTP server communication is encrypted with TLS (this can be via `STARTTLS`) or `HOST=localhost`. See [Email Setup]({{< relref "doc/usage/email-setup.en-us.md" >}}) for more information.
- `SEND_AS_PLAIN_TEXT`: **false**: Send mails as plain text.
- `SKIP_VERIFY`: **false**: Whether or not to skip verification of certificates; `true` to disable verification.
- **Warning:** This option is unsafe. Consider adding the certificate to the system trust store instead.
- **Note:** Gitea only supports SMTP with STARTTLS.
- `USE_CERTIFICATE`: **false**: Use client certificate.
- `CERT_FILE`: **custom/mailer/cert.pem**
- `KEY_FILE`: **custom/mailer/key.pem**
- Please note: authentication is only supported when the SMTP server communication is encrypted with TLS (this can be via `STARTTLS`) or SMTP host is localhost. See [Email Setup]({{< relref "doc/usage/email-setup.en-us.md" >}}) for more information.
- `ENABLE_HELO`: **true**: Enable HELO operation.
- `HELO_HOSTNAME`: **(retrieved from system)**: HELO hostname.
- `FROM`: **\<empty\>**: Mail from address, RFC 5322. This can be just an email address, or the "Name" \<email@example.com\> format.
- `ENVELOPE_FROM`: **\<empty\>**: Address set as the From address on the SMTP mail envelope. Set to `<>` to send an empty address.
- `SUBJECT_PREFIX`: **\<empty\>**: Prefix to be placed before e-mail subject lines.
- **sendmail** Use the operating system's `sendmail` command instead of SMTP.
This is common on Linux systems.
- **dummy** Send email messages to the log as a testing phase.
- Note that enabling sendmail will ignore all other `mailer` settings except `ENABLED`,
`FROM`, `SUBJECT_PREFIX` and `SENDMAIL_PATH`.
- Enabling dummy will ignore all settings except `ENABLED`, `SUBJECT_PREFIX` and `FROM`.
- `SENDMAIL_PATH`: **sendmail**: The location of sendmail on the operating system (can be
command or full path).
- `SENDMAIL_ARGS`: **_empty_**: Specify any extra sendmail arguments. (NOTE: you should be aware that email addresses can look like options - if your `sendmail` command takes options you must set the option terminator `--`)
- `SENDMAIL_PATH`: **sendmail**: The location of sendmail on the operating system (can be command or full path).
- `SENDMAIL_ARGS`: **\<empty\>**: Specify any extra sendmail arguments. (NOTE: you should be aware that email addresses can look like options - if your `sendmail` command takes options you must set the option terminator `--`)
- `SENDMAIL_TIMEOUT`: **5m**: default timeout for sending email through sendmail
- `SENDMAIL_CONVERT_CRLF`: **true**: Most versions of sendmail prefer LF line endings rather than CRLF line endings. Set this to false if your version of sendmail requires CRLF line endings.
- `SEND_BUFFER_LEN`: **100**: Buffer length of mailing queue. **DEPRECATED** use `LENGTH` in `[queue.mailer]`
- `SEND_AS_PLAIN_TEXT`: **false**: Send mails only in plain text, without HTML alternative.
