Implementations

impl<T: AsRef<str> + PartialEq + Eq + Hash> SmtpClientBuilder<T>

pub fn new(hostname: T, port: u16) -> Self

pub fn allow_invalid_certs(self) -> Self

Allow invalid TLS certificates

pub fn implicit_tls(self, tls_implicit: bool) -> Self

Start connection in TLS or upgrade with STARTTLS

pub fn lmtp(self, is_lmtp: bool) -> Self

Use LMTP instead of SMTP

pub fn say_ehlo(self, say_ehlo: bool) -> Self

pub fn helo_host(self, host: impl Into<String>) -> Self

Set the EHLO/LHLO hostname

pub fn credentials(self, credentials: impl Into<Credentials<T>>) -> Self

Sets the authentication credentials

pub fn timeout(self, timeout: Duration) -> Self

Sets the SMTP connection timeout

pub fn local_ip(self, local_ip: IpAddr) -> Self

Sets the local IP to use while sending the email.

This is useful if your machine has multiple public IPs assigned and you want to ensure that you are using the intended one. Using an IP with good repudiation is quite important when you want to ensure deliverability.

NOTE: If the IP is not available on that machine, the [connect] and [connect_plain] will return and error

pub async fn connect(&self) -> Result<SmtpClient<TlsStream<TcpStream>>>

Connect over TLS

pub async fn connect_plain(&self) -> Result<SmtpClient<TcpStream>>

Connect over clear text (should not be used)

Trait Implementations

impl<T: Clone + AsRef<str> + PartialEq + Eq + Hash> Clone for SmtpClientBuilder<T>

fn clone(&self) -> SmtpClientBuilder<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
