 3. Set the following plugin settings via `.env` or `putenv()` in `config.php`:
 
-	- `TTRSS_SMTP_SERVER` - Send outgoing mail via this server (hostname:port). Required.
-	- `TTRSS_SMTP_LOGIN`, `TTRSS_SMTP_PASSWORD` - SMTP login/password, if needed.
-	- `TTRSS_SMTP_SECURE` - Use secure connection. Allowed values: `ssl`, `tls`, or empty.
-	- `TTRSS_SMTP_SKIP_CERT_CHECKS` - Accept all SSL certificates, use with caution.
-	- `TTRSS_SMTP_CA_FILE` - Use a custom CA certificate for SSL/TLS secure connections. Only used if TTRSS_SMTP_SKIP_CERT_CHECKS is false.
