Variants

Ehlo

Fields

domain_or_address: DomainOrAddress

domain_or_address: DomainOrAddress

Mail

Fields

reverse_path: String

parameters: Vec<Parameter>

Rcpt

Fields

forward_path: String

parameters: Vec<Parameter>

Data

Rset

Vrfy

This command asks the receiver to confirm that the argument identifies a user or mailbox. If it is a user name, information is returned as specified in Section 3.5.

This command has no effect on the reverse-path buffer, the forward- path buffer, or the mail data buffer.

Fields

user_or_mailbox: AtomOrQuoted

Expn

This command asks the receiver to confirm that the argument identifies a mailing list, and if so, to return the membership of that list. If the command is successful, a reply is returned containing information as described in Section 3.5. This reply will have multiple lines except in the trivial case of a one-member list.

This command has no effect on the reverse-path buffer, the forward- path buffer, or the mail data buffer, and it may be issued at any time.

Fields

mailing_list: AtomOrQuoted

Help

This command causes the server to send helpful information to the client. The command MAY take an argument (e.g., any command name) and return more specific information as a response.

SMTP servers SHOULD support HELP without arguments and MAY support it with arguments.

This command has no effect on the reverse-path buffer, the forward- path buffer, or the mail data buffer, and it may be issued at any time.

Fields

argument: Option<AtomOrQuoted>

Noop

This command does not affect any parameters or previously entered commands. It specifies no action other than that the receiver send a “250 OK” reply.

If a parameter string is specified, servers SHOULD ignore it.

This command has no effect on the reverse-path buffer, the forward- path buffer, or the mail data buffer, and it may be issued at any time.

Fields

argument: Option<AtomOrQuoted>

Quit

This command specifies that the receiver MUST send a “221 OK” reply, and then close the transmission channel.

The receiver MUST NOT intentionally close the transmission channel until it receives and replies to a QUIT command (even if there was an error). The sender MUST NOT intentionally close the transmission channel until it sends a QUIT command, and it SHOULD wait until it receives the reply (even if there was an error response to a previous command). If the connection is closed prematurely due to violations of the above or system or network failure, the server MUST cancel any pending transaction, but not undo any previously completed transaction, and generally MUST act as if the command or transaction in progress had received a temporary error (i.e., a 4yz response).

The QUIT command may be issued at any time. Any current uncompleted mail transaction will be aborted.

AuthPlain(Option<String>)

Implementations

impl Command

pub fn name(&self) -> &'static str

pub fn serialize(&self, writer: &mut impl Write) -> Result<()>

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Command

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Command

fn eq(&self, other: &Command) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
