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
Topics:
HELO EHLO MAIL RCPT DATA
RSET NOOP QUIT HELP VRFY

For more info use "HELP ".
To report bugs in the implementation send email to
sendmail-bugs@sendmail.org.
For local information send email to Postmaster at your site.
End of HELP info

These exceptions are generated in some instances when the SMTP
server returns an error code. The error code is stored in the
`smtp_code' attribute of the error, and the `smtp_error' attribute
is set to the error message.

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 for the
HELO/EHLO command. Otherwise, the local hostname is found using
socket.getfqdn().

The arguments are:

- password: The password for the authentication.
If there has been no previous EHLO or HELO command this session, this
method tries ESMTP EHLO first.
This method will return normally if the authentication was successful.
This method may raise the following exceptions:

SMTPAuthenticationError The server didn't accept the username/
password combination.

the identity of the SMTP server and client can be checked. This,
however, depends on whether the socket module really checks the

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 has the same meaning as it does 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.t lhloR! c C s t j | | | | d S( s Initialize a new instance.N( R
