There is no from parameter. · SMTP_HOST=Hostname of the SMTP server, e.g. smtp.example.net. · SMTP_INSECURE_TLS=Set to "true" to accept self-signed certificates. Prefer a proper internal CA. · SMTP_MAX_ATTACHMENT_BYTES=Maximum size of a single attachment. Default 5242880. · SMTP_MAX_MESSAGE_BYTES=Maximum size of the composed message. Default 10485760. · SMTP_MAX_RECIPIENTS=Maximum distinct recipients across To, Cc and Bcc in one message. Default 10. · SMTP_MAX_SENDS_PER_HOUR=Sliding hourly cap on messages sent.

Defaults to 587 for starttls, 465 for implicit, 25 for none. · SMTP_SIGNATURE=Text appended below the standard signature delimiter of every message. · SMTP_TLS=starttls (default), implicit or none. STARTTLS is required, never opportunistic. · SMTP_USER=Username for SMTP authentication.
