This should follow RFC 821 (SMTP), RFC 1869 (ESMTP), RFC 2554 (SMTP
Authentication) and RFC 2487 (Secure SMTP over TLS).
Notes:
Please remember, when doing ESMTP, that the names of the SMTP service
extensions are NOT the same thing as the option keywords for the RCPT
and MAIL commands!
Example:
>>> import smtplib
>>> s=smtplib.SMTP("localhost")
>>> print(s.help())
This is Sendmail version 8.8.4

To report bugs in the implementation send email to

For local information send email to Postmaster at your site.

SMTP Objects:
SMTP objects have the following attributes:
helo_resp
This is the message given by the server in response to the
most recent HELO command.
ehlo_resp
This is the message given by the server in response to the
most recent EHLO command. This is usually multiline.
does_esmtp
This is a True value _after you do an EHLO command_, if the
server supports ESMTP.
esmtp_features
This is a dictionary, which, if the server supports ESMTP,
will _after you do an EHLO command_, contain the names of the
SMTP service extensions this server supports, and their
parameters (if any).
Note, all extension names are mapped to lower case in the
dictionary.
See each method's docstrings for details. In general, there is a
method of the same name to perform each SMTP command. There is also a
method called 'sendmail' that will do an entire mail transaction.

If specified, `host' is the name of the remote host to which to
connect. If specified, `port' specifies the port to which to connect.
By default, smtplib.SMTP_PORT is used. If a host is specified the
connect method is called, and if it returns anything other than a
success code an SMTPConnectError is raised. If specified,
`local_hostname` is used as the FQDN of the local host in the HELO/EHLO
command. Otherwise, the local hostname is found using
socket.getfqdn(). The `source_address` parameter takes a 2-tuple (host,
port) for the socket to bind to as its source address before
connecting. If the host is '' and port is 0, the OS default behavior
will be used.

a Puts the connection to the SMTP server into TLS mode.
If there has been no previous EHLO or HELO command this session, this
method tries ESMTP EHLO first.
If the server supports TLS, this will encrypt the rest of the SMTP
session. If you provide the keyfile and certfile parameters,
the identity of the SMTP server and client can be checked. This,
however, depends on whether the socket module really checks the
certificates.
This method may raise the following exceptions:

The arguments are as for sendmail, except that msg is an
email.message.Message object. If from_addr is None or to_addrs is
None, these arguments are taken from the headers of the Message as
described in RFC 2822 (a ValueError is raised if there is more than
one set of 'Resent-' headers). Regardless of the values of from_addr and
to_addr, any Bcc field (or Resent-Bcc field, when the Message is a
resent) of the Message object won't be transmitted. The Message
object is then serialized using email.generator.BytesGenerator and
sendmail is called to transmit the message.

encrypted socket (to use this class you need a socket module that was
compiled with SSL support). If host is not specified, '' (the local
host) is used. If port is omitted, the standard SMTP-over-SSL port
(465) is used. local_hostname and source_address have the same meaning
as they do in the SMTP class. keyfile and certfile are also optional -
they can contain a PEM formatted private key and certificate chain file
for the SSL connection. context also optional, can contain a
SSLContext, and is an alternative to keyfile and certfile; If it is
specified both keyfile and certfile must be None.

Z d S) LMTPa LMTP - Local Mail Transfer Protocol
The LMTP protocol, which is very similar to ESMTP, is heavily based
on the standard SMTP client. It's common to use Unix sockets for
LMTP, so our connect() method must support that as well as a regular
host:port server. local_hostname and source_address have the same
meaning as they do in the SMTP class. To specify a Unix socket,
you must use an absolute path as the host, starting with a '/'.
Authentication is supported, using the regular SMTP mechanism. When
using a Unix socket, LMTP generally don't support or require any
authentication, but your mileage might vary.Zlhlor Nc C s# t j | | | d | d | d S)zInitialize a new instance.r9 r7 N)r r )r r; r< r9 r7 r r r r s z
