:mod:`smtplib` --- SMTP protocol client
=======================================

.. module:: smtplib
   :synopsis: SMTP protocol client (requires sockets).
.. sectionauthor:: Eric S. Raymond <esr@snark.thyrsus.com>

.. index::
   pair: SMTP; protocol
   single: Simple Mail Transfer Protocol

**Source code:** :source:`Lib/smtplib.py`

--------------

The :mod:`smtplib` module defines an SMTP client session object that can be used
to send mail to any Internet machine with an SMTP or ESMTP listener daemon.  For
details of SMTP and ESMTP operation, consult :rfc:`821` (Simple Mail Transfer
Protocol) and :rfc:`1869` (SMTP Service Extensions).

.. class:: SMTP([host[, port[, local_hostname[, timeout]]]])

An :class:`SMTP` instance encapsulates an SMTP connection.  It has methods
   that support a full repertoire of SMTP and ESMTP operations. If the optional
   host and port parameters are given, the SMTP :meth:`connect` method is
   called with those parameters during initialization.  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
   :func:`socket.getfqdn`.  If the :meth:`connect` call returns anything other
   than a success code, an :exc:`SMTPConnectError` is raised. The optional
   *timeout* parameter specifies a timeout in seconds for blocking operations
   like the connection attempt (if not specified, the global default timeout
   setting will be used).  If the timeout expires, :exc:`socket.timeout`
   is raised.

For normal use, you should only require the initialization/connect,
   :meth:`sendmail`, and :meth:`SMTP.quit` methods.
   An example is included below.

.. versionchanged:: 2.6
      *timeout* was added.

.. class:: SMTP_SSL([host[, port[, local_hostname[, keyfile[, certfile[, timeout]]]]]])

An :class:`SMTP_SSL` instance behaves exactly the same as instances of
   :class:`SMTP`. :class:`SMTP_SSL` should be used for situations where SSL is
   required from the beginning of the connection and using :meth:`starttls` is
   not appropriate. 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* has the same meaning as it does for the :class:`SMTP`
   class.  *keyfile* and *certfile* are also optional, and can contain a PEM
   formatted private key and certificate chain file for the SSL connection. The
   optional *timeout* parameter specifies a timeout in seconds for blocking
   operations like the connection attempt (if not specified, the global default
   timeout setting will be used).  If the timeout expires, :exc:`socket.timeout`
   is raised.

.. versionadded:: 2.6

.. class:: LMTP([host[, port[, local_hostname]]])

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
   :meth:`connect` method must support that as well as a regular host:port
   server.  *local_hostname* has the same meaning as it does for the
   :class:`SMTP` class.  To specify a Unix socket, you must use an absolute
   path for *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.

.. versionadded:: 2.6

A nice selection of exceptions is defined as well:

.. exception:: SMTPException

The base exception class for all the other exceptions provided by this
   module.

.. exception:: SMTPServerDisconnected

This exception is raised when the server unexpectedly disconnects, or when an
   attempt is made to use the :class:`SMTP` instance before connecting it to a
   server.

.. exception:: SMTPResponseException

Base class for all exceptions that include an SMTP error code. These exceptions
   are generated in some instances when the SMTP server returns an error code.  The
   error code is stored in the :attr:`smtp_code` attribute of the error, and the
   :attr:`smtp_error` attribute is set to the error message.

.. exception:: SMTPSenderRefused

Sender address refused.  In addition to the attributes set by on all
   :exc:`SMTPResponseException` exceptions, this sets 'sender' to the string that
   the SMTP server refused.

.. exception:: SMTPRecipientsRefused

All recipient addresses refused.  The errors for each recipient are accessible
   through the attribute :attr:`recipients`, which is a dictionary of exactly the
   same sort as :meth:`SMTP.sendmail` returns.

.. exception:: SMTPDataError

The SMTP server refused to accept the message data.

.. exception:: SMTPConnectError

Error occurred during establishment of a connection  with the server.

.. exception:: SMTPHeloError

The server refused our ``HELO`` message.

.. exception:: SMTPAuthenticationError

SMTP authentication went wrong.  Most probably the server didn't accept the
   username/password combination provided.

      Protocol definition for SMTP.  This document covers the model, operating
      procedure, and protocol details for SMTP.

:rfc:`1869` - SMTP Service Extensions
      Definition of the ESMTP extensions for SMTP.  This describes a framework for
      extending SMTP with new commands, supporting dynamic discovery of the commands
      provided by the server, and defines a few additional commands.

.. _smtp-objects:

SMTP Objects
------------

An :class:`SMTP` instance has the following methods:

.. method:: SMTP.set_debuglevel(level)

Set the debug output level.  A true value for *level* results in debug messages
   for connection and for all messages sent to and received from the server.

.. method:: SMTP.docmd(cmd, [, argstring])

Send a command *cmd* to the server.  The optional argument *argstring* is simply
   concatenated to the command, separated by a space.

This returns a 2-tuple composed of a numeric response code and the actual
   response line (multiline responses are joined into one long line.)

In normal operation it should not be necessary to call this method explicitly.
   It is used to implement other methods and may be useful for testing private
   extensions.

If the connection to the server is lost while waiting for the reply,
   :exc:`SMTPServerDisconnected` will be raised.

.. method:: SMTP.connect([host[, port]])

Connect to a host on a given port.  The defaults are to connect to the local
   host at the standard SMTP port (25). If the hostname ends with a colon (``':'``)
   followed by a number, that suffix will be stripped off and the number
   interpreted as the port number to use. This method is automatically invoked by
   the constructor if a host is specified during instantiation.  Returns a
   2-tuple of the response code and message sent by the server in its
   connection response.

.. method:: SMTP.helo([hostname])

Identify yourself to the SMTP server using ``HELO``.  The hostname argument
   defaults to the fully qualified domain name of the local host.
   The message returned by the server is stored as the :attr:`helo_resp` attribute
   of the object.

In normal operation it should not be necessary to call this method explicitly.
   It will be implicitly called by the :meth:`sendmail` when necessary.

.. method:: SMTP.ehlo([hostname])

Identify yourself to an ESMTP server using ``EHLO``.  The hostname argument
   defaults to the fully qualified domain name of the local host.  Examine the
   response for ESMTP option and store them for use by :meth:`has_extn`.
   Also sets several informational attributes: the message returned by
   the server is stored as the :attr:`ehlo_resp` attribute, :attr:`does_esmtp`
   is set to true or false depending on whether the server supports ESMTP, and
   :attr:`esmtp_features` will be a dictionary containing the names of the
   SMTP service extensions this server supports, and their
   parameters (if any).

Unless you wish to use :meth:`has_extn` before sending mail, it should not be
   necessary to call this method explicitly.  It will be implicitly called by
   :meth:`sendmail` when necessary.

.. method:: SMTP.ehlo_or_helo_if_needed()

This method call :meth:`ehlo` and or :meth:`helo` if there has been no
   previous ``EHLO`` or ``HELO`` command this session.  It tries ESMTP ``EHLO``
   first.

:exc:`SMTPHeloError`
     The server didn't reply properly to the ``HELO`` greeting.

.. versionadded:: 2.6

.. method:: SMTP.has_extn(name)

Return :const:`True` if *name* is in the set of SMTP service extensions returned
   by the server, :const:`False` otherwise. Case is ignored.

.. method:: SMTP.verify(address)

Check the validity of an address on this server using SMTP ``VRFY``. Returns a
   tuple consisting of code 250 and a full :rfc:`822` address (including human
   name) if the user address is valid. Otherwise returns an SMTP error code of 400
   or greater and an error string.

.. note::

Many sites disable SMTP ``VRFY`` in order to foil spammers.

.. method:: SMTP.login(user, password)

Log in on an SMTP server that requires authentication. The arguments are the
   username and the password to authenticate with. 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, or
   may raise the following exceptions:

:exc:`SMTPHeloError`
      The server didn't reply properly to the ``HELO`` greeting.

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

:exc:`SMTPException`
      No suitable authentication method was found.

.. method:: SMTP.starttls([keyfile[, certfile]])

Put the SMTP connection in TLS (Transport Layer Security) mode.  All SMTP
   commands that follow will be encrypted.  You should then call :meth:`ehlo`
   again.

If *keyfile* and *certfile* are provided, these are passed to the :mod:`socket`
   module's :func:`ssl` function.

If there has been no previous ``EHLO`` or ``HELO`` command this session,
   this method tries ESMTP ``EHLO`` first.

.. versionchanged:: 2.6

:exc:`SMTPHeloError`
      The server didn't reply properly to the ``HELO`` greeting.

:exc:`SMTPException`
     The server does not support the STARTTLS extension.

.. versionchanged:: 2.6

:exc:`RuntimeError`
     SSL/TLS support is not available to your Python interpreter.

.. method:: SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options])

Send mail.  The required arguments are an :rfc:`822` from-address string, a list
   of :rfc:`822` to-address strings (a bare string will be treated as a list with 1
   address), and a message string.  The caller may pass a list of ESMTP options
   (such as ``8bitmime``) to be used in ``MAIL FROM`` commands as *mail_options*.
   ESMTP options (such as ``DSN`` commands) that should be used with all ``RCPT``
   commands can be passed as *rcpt_options*.  (If you need to use different ESMTP
   options to different recipients you have to use the low-level methods such as
   :meth:`mail`, :meth:`rcpt` and :meth:`data` to send the message.)

.. note::

The *from_addr* and *to_addrs* parameters are used to construct the message
      envelope used by the transport agents. The :class:`SMTP` does not modify the
      message headers in any way.

If there has been no previous ``EHLO`` or ``HELO`` command this session, this
   method tries ESMTP ``EHLO`` first. If the server does ESMTP, message size and
   each of the specified options will be passed to it (if the option is in the
   feature set the server advertises).  If ``EHLO`` fails, ``HELO`` will be tried
   and ESMTP options suppressed.

This method will return normally if the mail is accepted for at least one
   recipient. Otherwise it will raise an exception.  That is, if this method does
   not raise an exception, then someone should get your mail. If this method does
   not raise an exception, it returns a dictionary, with one entry for each
   recipient that was refused.  Each entry contains a tuple of the SMTP error code
   and the accompanying error message sent by the server.

This method may raise the following exceptions:

:exc:`SMTPRecipientsRefused`
      All recipients were refused.  Nobody got the mail.  The :attr:`recipients`
      attribute of the exception object is a dictionary with information about the
      refused recipients (like the one returned when at least one recipient was
      accepted).

:exc:`SMTPHeloError`
      The server didn't reply properly to the ``HELO`` greeting.

:exc:`SMTPSenderRefused`
      The server didn't accept the *from_addr*.

:exc:`SMTPDataError`
      The server replied with an unexpected error code (other than a refusal of a
      recipient).

Unless otherwise noted, the connection will be open even after an exception is
   raised.

.. method:: SMTP.quit()

Terminate the SMTP session and close the connection.  Return the result of
   the SMTP ``QUIT`` command.

.. versionchanged:: 2.6
      Return a value.

Low-level methods corresponding to the standard SMTP/ESMTP commands ``HELP``,
``RSET``, ``NOOP``, ``MAIL``, ``RCPT``, and ``DATA`` are also supported.
Normally these do not need to be called directly, so they are not documented
here.  For details, consult the module code.

.. _smtp-example:

SMTP Example
------------

This example prompts the user for addresses needed in the message envelope ('To'
and 'From' addresses), and the message to be delivered.  Note that the headers
to be included with the message must be included in the message as entered; this
example doesn't do any processing of the :rfc:`822` headers.  In particular, the
'To' and 'From' addresses must be included in the message headers explicitly. ::

import smtplib

def prompt(prompt):
       return raw_input(prompt).strip()

fromaddr = prompt("From: ")
   toaddrs  = prompt("To: ").split()
   print "Enter message, end with ^D (Unix) or ^Z (Windows):"

# Add the From: and To: headers at the start!
   msg = ("From: %s\r\nTo: %s\r\n\r\n"
          % (fromaddr, ", ".join(toaddrs)))
   while 1:
       try:
           line = raw_input()
       except EOFError:
           break
       if not line:
           break
       msg = msg + line

print "Message length is " + repr(len(msg))

server = smtplib.SMTP('localhost')
   server.set_debuglevel(1)
   server.sendmail(fromaddr, toaddrs, msg)
   server.quit()

.. note::

In general, you will want to use the :mod:`email` package's features to
   construct an email message, which you can then convert to a string and send
   via :meth:`sendmail`; see :ref:`email-examples`.

:mod:`smtplib` --- SMTP protocol client ======================================= .. module:: smtplib :synopsis: SMTP protocol client (requires sockets). .. sectionauthor:: Eric S. Raymond .. index:: pair: SMTP; protocol single: Simple Mail Transfer Protocol **Source code:** :source:`Lib/smtplib.py` -------------- The :mod:`smtplib` module defines an SMTP client session object that can be used to send mail to any Internet machine with an SMTP or ESMTP listener daemon. For details of SMTP and ESMTP operation, consult :rfc:`821` (Simple Mail Transfer Protocol) and :rfc:`1869` (SMTP Service Extensions). .. class:: SMTP([host[, port[, local_hostname[, timeout]]]]) An :class:`SMTP` instance encapsulates an SMTP connection. It has methods that support a full repertoire of SMTP and ESMTP operations. If the optional host and port parameters are given, the SMTP :meth:`connect` method is called with those parameters during initialization. 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 :func:`socket.getfqdn`. If the :meth:`connect` call returns anything other than a success code, an :exc:`SMTPConnectError` is raised. The optional *timeout* parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not specified, the global default timeout setting will be used). If the timeout expires, :exc:`socket.timeout` is raised. For normal use, you should only require the initialization/connect, :meth:`sendmail`, and :meth:`SMTP.quit` methods. An example is included below. .. versionchanged:: 2.6 *timeout* was added. .. class:: SMTP_SSL([host[, port[, local_hostname[, keyfile[, certfile[, timeout]]]]]]) An :class:`SMTP_SSL` instance behaves exactly the same as instances of :class:`SMTP`. :class:`SMTP_SSL` should be used for situations where SSL is required from the beginning of the connection and using :meth:`starttls` is not appropriate. 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* has the same meaning as it does for the :class:`SMTP` class. *keyfile* and *certfile* are also optional, and can contain a PEM formatted private key and certificate chain file for the SSL connection. The optional *timeout* parameter specifies a timeout in seconds for blocking operations like the connection attempt (if not specified, the global default timeout setting will be used). If the timeout expires, :exc:`socket.timeout` is raised. .. versionadded:: 2.6 .. class:: LMTP([host[, port[, local_hostname]]]) The LMTP protocol, which is very similar to ESMTP, is heavily based on the standard SMTP client.
