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 EXPN VERB ETRN DSN For more info use "HELP <topic>". To report bugs in the implementation send email to sendmail-bugs@sendmail.org. 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. r N�ehlor& c C s� || _ || _i | _d| _|| _d| _|rR| �||�\}}|dkrR| �� t||��|durb|| _ nNt � � }d|v rz|| _ n6d} zt � t � � �} W n t jy� Y n0 d| | _ dS )a Initialize 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. �asciir �� N�.z 127.0.0.1z[%s])�_host�timeout�esmtp_features�command_encoding�source_address�_auth_challenge_count�connect�closer �local_hostname�socketZgetfqdnZ gethostbynameZ gethostnameZgaierror) r �host�portrE r> rA r r Zfqdnr. r r r r! � s, z SMTP.__init__c C s | S r r �r r r r � __enter__ s zSMTP.__enter__c G sT zDz$| � d�\}}|dkr$t||��W n ty8 Y n0 W | �� n | �� 0 d S )NZQUIT�� )�docmdr r rD )r r r �messager r r �__exit__ s z SMTP.__exit__c C s || _ dS )z�Set the debug output level.

The arguments are: - from_addr : The address sending this mail. - to_addrs : A list of addresses to send this mail to. A bare string will be treated as a list with 1 address. - msg : The message to send. - mail_options : List of ESMTP options (such as 8bitmime) for the mail command. - rcpt_options : List of ESMTP options (such as DSN commands) for all the rcpt commands. msg may be a string containing characters in the ASCII range, or a byte string. A string is encoded to bytes using the ascii codec, and lone \r and \n characters are converted to \r\n characters. 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 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. 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: SMTPHeloError The server didn't reply properly to the helo greeting. SMTPRecipientsRefused The server rejected ALL recipients (no mail was sent). SMTPSenderRefused The server didn't accept the from_addr. SMTPDataError The server replied with an unexpected error code (other than a refusal of a recipient). SMTPNotSupportedError The mail_options parameter includes 'SMTPUTF8' but the SMTPUTF8 extension is not supported by the server. Note: the connection will be open even after an exception is raised. Example: >>> import smtplib >>> s=smtplib.SMTP("localhost") >>> tolist=["one@one.org","two@two.org","three@three.org","four@four.org"] >>> msg = '''\ ... From: Me@my.org ... Subject: testin'... ... ... This is a test ''' >>> s.sendmail("me@my.org",tolist,msg) { "three@three.org" : ( 550 ,"User unknown" ) } >>> s.quit() In the above example, the message was accepted for delivery to three of the four addresses, and one was rejected, with the error code 550. If all addresses are accepted, then the method will return an empty dictionary. r: �sizezsize=%dr� i� � )r� rk rl r8 rm r� r� r r~ r� rD r� r r� r r6 r ) r � from_addr�to_addrsr � mail_options� rcpt_optionsZ esmtp_optsZoptionr r� Zsenderrsr� r r r �sendmail( sF @ z SMTP.sendmailc C s� | � � |�d�}|du r d}nt|�dkr2d}ntd��|du r||d |v rZ||d n ||d }tj�|g�d d }|du r�d d � ||d ||d ||d fD �}dd � tj�|�D �}t�|�} | d = | d= d} zd�|g|��� d� W n, t �y& | � d��s t d��d} Y n0 t �� �f} | �rftjj| |jjdd�d�} g |�d�d�R }n tj�| �} | j| dd� | �� } W d � n1 �s�0 Y | �||| ||�S ) a~ Converts message to a bytestring and passes it to sendmail. 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& rQ zResent-z0message has more than one 'Resent-' header blockZSender�Fromr c S s g | ]}|d ur|�qS r r )r� �fr r r r� � s �z%SMTP.send_message.<locals>.<listcomp>�ToZBccZCcc S s g | ] }|d �qS )rQ r )r� �ar r r r� � r� z Resent-BccFr: r� z�One or more source or delivery addresses require internationalized email support, but the server does not advertise the required SMTPUTF8 capabilityT)�utf8)�policyZSMTPUTF8z BODY=8BITMIMEr )�linesep)r� Zget_allr~ r[ r( r) Z getaddresses�copyr� rm �UnicodeEncodeErrorr� r �io�BytesIO� generatorZBytesGeneratorr� ZcloneZflatten�getvaluer� )r r r� r� r� r� ZresentZ header_prefixZ addr_fieldsZmsg_copyZ internationalZbytesmsg�gZflatmsgr r r � send_message� sV � � � � � ( �zSMTP.send_messagec C sT z4| j }d| _ |r|�� W | j}d| _|rP|�� n| j}d| _|rN|�� 0 dS )z(Close the connection to the SMTP server.N)rR rD rf )r rR rf r r r rD � s �z SMTP.closec C s. | � d�}d | _| _i | _d| _| �� |S )zTerminate the SMTP session.�quitNF)rL r� r� r? r� rD )r �resr r r r� � s z SMTP.quit)r] r N)r& )r& )r& )r& )r& )r )r )N)N)N)NNN)r r )NNr r )2r r r r rO rf rR r� r� r� r� � SMTP_PORTrd rF �_GLOBAL_DEFAULT_TIMEOUTr! rJ rN rP rY r\ rC ro ru rg rL r� r9 r� r� r� r� r� r� r� r6 r� r� r� r� r� r� r� r� r� r� r� r� rD r� r r r r r � sf � 0 ! 1 3 0 B 8 � h � M r c s@ e Zd ZdZeZdddddejddfdd�Z� fdd�Z � Z S ) �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). 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. r& r Nc C s� |d ur|d urt d��|d ur0|d ur0t d��|d us@|d urVdd l} | �dtd� || _|| _|d u rxtj||d�}|| _t � | |||||� d S )Nr� r� r r� r� r� ) r[ r� r� r� r� r� r� r� r� r r! ) r rG rH rE r� r� r> rA r� r� r r r r! s& ���zSMTP_SSL.__init__c s@ | j dkr| �d||f� t� �|||�}| jj|| jd�}|S )Nr r_ r� )rO rY �superr\ r� r� r= )r rG rH r> Z new_socket�� __class__r r r\ s �zSMTP_SSL._get_socket) r r r r � SMTP_SSL_PORTrd rF r� r! r\ � __classcell__r r r� r r� � s � r� i� c s@ e Zd ZdZdZdeddejf� fdd� Zd � fd d � Z � Z 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 s t � j|||||d� dS )zInitialize a new instance.)rE rA r> N)r� r! )r rG rH rE rA r> r� r r r! < s �z LMTP.__init__r] r c s� |d dkr t � j|||d�S | jdur6| js6td��zBt�tjtj�| _| jtjurd| j� | j� d| _ | j�|� W n@ t y� | j dkr�| � d|� | jr�| j�� d| _� Y n0 | �� \}}| j dkr�| � d|� ||fS )z=Connect to the LMTP daemon, on either a Unix or a TCP socket.r �/)rA NrZ z connect fail:r_ )r� rC r> r[ rF ZAF_UNIXZ SOCK_STREAMrf r� Z settimeoutrR rc rO rY rD rg )r rG rH rA r r r� r r rC B s* z LMTP.connect)r] r N) r r r r r� � LMTP_PORTrF r� r! rC r� r r r� r r , s �r �__main__c C s( t j�| d � t j�� t j�� �� S )Nz: )rV �stdout�write�flush�stdinr| r+ )�promptr r r r a s r r� r� �,zEnter message, end with ^D:r& zMessage length is %dr] rQ )Ar rF r� r2 Z email.utilsr( Z email.messageZemail.generatorr� r� r� rT rV Zemail.base64mimer r� �__all__r� r� r4 r� r} r� �compile�Ir� rc r r r r r r r r r r r r/ r r7 r8 r� � ImportErrorr� r r� r r r r r Zfromaddrr� ZtoaddrsrS r r r| r� r~ ZserverrP r� r� r r r r �<module> s� ) </ 4
