SMTP client for sending emails.
After the client has connected to the SMTP server, it repeatedly calls
L{SMTPClient.getMailFrom}, L{SMTPClient.getMailTo} and
L{SMTPClient.getMailData} and uses this information to send an email.
It then calls L{SMTPClient.getMailFrom} again; if it returns L{None}, the
client will disconnect, otherwise it will continue as normal i.e. call
L{SMTPClient.getMailTo} and L{SMTPClient.getMailData} and send a new email.

Build an L{ESMTPSender} protocol configured with C{heloFallback},
C{requireAuthentication}, and C{requireTransportSecurity} as specified
in L{__init__}.
This sets L{currentProtocol} on the factory, as well as returning it.

Send an email.
This interface is intended to be a replacement for L{smtplib.SMTP.sendmail}
and related methods. To maintain backwards compatibility, it will fall back
to plain SMTP, if ESMTP support is not available. If ESMTP support is
available, it will attempt to provide encryption via STARTTLS and
authentication if a secret is provided.
@param smtphost: The host the message should be sent to.
@type smtphost: L{bytes}
@param from_addr: The (envelope) address sending this mail.
@type from_addr: L{bytes}
@param to_addrs: A list of addresses to send this mail to. A string will
be treated as a list of one address.
@type to_addr: L{list} of L{bytes} or L{bytes}
@param msg: The message, including headers, either as a file or a string.
File-like objects need to support read() and close(). Lines must be
delimited by '\n'. If you pass something that doesn't look like a file,
we try to convert it to a string (so you should be able to pass an
L{email.message} directly, but doing the conversion with
L{email.generator} manually will give you more control over the process).
@param senderDomainName: Name by which to identify. If None, try to pick
something sane (but this depends on external configuration and may not
succeed).
@type senderDomainName: L{bytes}
@param port: Remote port to which to connect.
@type port: L{int}
@param username: The username to use, if wanting to authenticate.
@type username: L{bytes} or L{unicode}
@param password: The secret to use, if wanting to authenticate. If you do
not specify this, SMTP authentication will not occur.
@type password: L{bytes} or L{unicode}
@param requireTransportSecurity: Whether or not STARTTLS is required.
@type requireTransportSecurity: L{bool}
@param requireAuthentication: Whether or not authentication is required.
@type requireAuthentication: L{bool}
@param reactor: The L{reactor} used to make the TCP connection.
@rtype: L{Deferred}
@returns: A cancellable L{Deferred}, its callback will be called if a
message is sent to ANY address, the errback if no message is sent. When
the C{cancel} method is called, it will stop retrying and disconnect
the connection immediately.
The callback will be called with a tuple (numOk, addresses) where numOk
is the number of successful recipient addresses and addresses is a list
of tuples (address, code, resp) giving the response to the RCPT command
for each address.

Cancel the L{twisted.mail.smtp.sendmail} call, tell the factory not to
retry and disconnect the connection.
