Interface Envelope

The SMTP envelope for a raw message, independent of the message headers.

interface Envelope {
from?: string;
to: readonly (string | EnvelopeRecipient)[];
}

Properties

The envelope sender. An empty or omitted value requests a null reverse-path, which is appropriate for bounce messages.

to: readonly (string | EnvelopeRecipient)[]

At least one envelope recipient. Each entry is a mailbox address or an EnvelopeRecipient carrying DSN parameters.
