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. rNehlor c Cs||_||_i|_d|_||_|rL|j||\}}|dkrL|jt|||dk r\||_nPt j }d|krt||_n8d} yt j t j } Wnt j k rYnXd| |_dS)aInitialize a new instance. 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. asciiN.z 127.0.0.1z[%s])_hosttimeoutesmtp_featurescommand_encodingsource_addressconnectcloser local_hostnamesocketZgetfqdnZ gethostbynameZ gethostnameZgaierror) rhostportr<r6r9rrZfqdnr)rrrrs* z SMTP.__init__cCs|S)Nr)rrrr __enter__szSMTP.__enter__cGsNz>y$|jd\}}|dkr$t||Wntk r:YnXWd|jXdS)NZQUIT)docmdrrr;)rrrmessagerrr__exit__s z SMTP.__exit__cCs ||_dS)zSet the debug output level.

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. If the sender or any of the recipient addresses contain non-ASCII and the server advertises the SMTPUTF8 capability, the policy is cloned with utf8 set to True for the serialization, and SMTPUTF8 and BODY=8BITMIME are asserted on the send. If the server does not support SMTPUTF8, an SMTPNotSupported error is raised. Otherwise the generator is called without modifying the policy. z Resent-DateNr rGzResent-z0message has more than one 'Resent-' header blockZSenderFromrcSsg|]}|dk r|qS)Nr)rfrrrrsz%SMTP.send_message..ToZBccZCccSsg|] }|dqS)rGr)rarrrrsz Resent-BccFr2rzOne or more source or delivery addresses require internationalized email support, but the server does not advertise the required SMTPUTF8 capabilityT)utf8)policySMTPUTF8 BODY=8BITMIMEz )linesep)rr)rZget_allrmrUr"r#Z getaddressescopyror_UnicodeEncodeErrorrrioBytesIO generatorZBytesGeneratorrZcloneZflattengetvaluer)rrrrrrZresentZ header_prefixZ addr_fieldsZmsg_copyZ internationalZbytesmsggZflatmsgrrr send_message|sJ           zSMTP.send_messagec Cs<z|j}d|_|r|jWd|j}d|_|r6|jXdS)z(Close the connection to the SMTP server.N)rHr;rX)rrHrXrrrr;s z SMTP.closecCs.|jd}d|_|_i|_d|_|j|S)zTerminate the SMTP session.quitNF)rBr}rur7r~r;)rresrrrrs   z SMTP.quit)rPrN)r )r )r )r )r )N)N)N)NNN)1rrrrrErHrur|r}r~ SMTP_PORTrWr=_GLOBAL_DEFAULT_TIMEOUTrr@rDrFrMrOr:rarcrYrBrtr1rrrrrrrr.rrrrryrrrrrrrr;rrrrrrs^ -   " 1  3    '  B 8 gL c@s8eZdZdZeZdddddejddfddZddZ dS) SMTP_SSLa This is a subclass derived from SMTP that connects over an SSL encrypted socket (to use this class you need a socket module that was compiled with SSL support).

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.
