Struct SmtpParameter 

pub struct SmtpParameter<'a> {
    pub keyword: SmtpAtom<'a>,
    pub value: Option<Cow<'a, str>>,
}

An ESMTP parameter (keyword[=value]).

Fields

keyword: SmtpAtom<'a>

The parameter keyword

value: Option<Cow<'a, str>>

The optional parameter value

Implementations

impl SmtpParameter<'static>

DSN parameter constructors for MAIL FROM and RCPT TO (RFC 3461).

pub fn envid(id: impl Into<String>) -> SmtpParameter<'static>

Build the ENVID=<id> parameter for MAIL FROM.

The envelope identifier is an opaque string chosen by the sender that uniquely identifies this mail transaction. It is included in any DSN generated for the message.

The value must contain only printable US-ASCII characters excluding = and whitespace (xtext encoding, RFC 3461 §4).

Reference

RFC 3461 §4.4

impl SmtpParameter<'static>

Original recipient parameter constructor for RCPT TO (RFC 3461).

pub fn orcpt_rfc822(address: impl Into<String>) -> SmtpParameter<'static>

Build the ORCPT=rfc822;<address> parameter for RCPT TO.

Specifies the original recipient address, before any aliasing or forwarding, so that DSNs can reference it.

Reference

RFC 3461 §4.2
