Arguments can be strings or integers (where appropriate) (e.g.: retr(1) and retr('1') both work equally well. Minimal Command Set: USER name user(name) PASS string pass_(string) STAT stat() LIST [msg] list(msg = None) RETR msg retr(msg) DELE msg dele(msg) NOOP noop() RSET rset() QUIT quit() Optional Commands (some servers support these): RPOP name rpop(name) APOP name digest apop(name, digest) TOP msg n top(msg, n) UIDL [msg] uidl(msg = None) CAPA capa() STLS stls() UTF8 utf8() Raises one exception: 'error_proto'. Instantiate with: POP3(hostname, port=110) NB: the POP protocol locks the mailbox from user authorization until QUIT, so be sure to get in, suck the messages, and quit, each time you access the mailbox. POP is a line-based protocol, which means large mail messages consume lots of python cycles reading them line-by-line. If it's available on your mail server, use IMAP4 instead, it doesn't suffer from the two problems above. zUTF-8c C sP || _ || _d| _t�d| ||� | �|�| _| j�d�| _d| _ | � � | _ d S )NFzpoplib.connect�rbr ) �host�port�_tls_established�sys�audit�_create_socket�sock�makefile�file� _debugging�_getresp�welcome)�selfr r �timeoutr r r �__init__b s z POP3.__init__c C s( |d ur|st d��t�| j| jf|�S )Nz0Non-blocking socket (timeout=0) is not supported)� ValueError�socket�create_connectionr r )r r r r r r m s zPOP3._create_socketc C s: | j dkrtdt|�� t�d| |� | j�|t � d S )N� z*put*zpoplib.putline)r �print�reprr r r �sendall�CRLF�r �liner r r �_putliner s z POP3._putlinec C s. | j rtdt|�� t|| j�}| �|� d S )Nz*cmd*)r r! r" �bytes�encodingr' r% r r r �_putcmdz s z POP3._putcmdc C s� | j �td �}t|�tkr$td��| jdkr<tdt|�� |sHtd��t|�}|dd � tkrp|d d� |fS |d d� t kr�|dd� |fS |d d� |fS )Nr z line too longz*get*z-ERR EOF������) r �readline�_MAXLINE�lenr r r! r" r$ �CR)r r& �octetsr r r �_getline� s z POP3._getlinec C s: | � � \}}| jdkr$tdt|�� |�d�s6t|��|S )Nr z*resp*� +)r2 r r! r" � startswithr )r �resp�or r r r � s z POP3._getrespc C sl | � � }g }d}| �� \}}|dkrb|�d�rB|d }|dd � }|| }|�|� | �� \}}q |||fS )Nr � .s ..r )r r2 r4 �append)r r5 �listr1 r& r6 r r r � _getlongresp� s zPOP3._getlongrespc C s | � |� | �� S �N)r* r r% r r r � _shortcmd� s zPOP3._shortcmdc C s | � |� | �� S r; )r* r: r% r r r �_longcmd� s z POP3._longcmdc C s | j S r; )r �r r r r � getwelcome� s zPOP3.getwelcomec C s || _ d S r; )r )r �levelr r r �set_debuglevel� s zPOP3.set_debuglevelc C s | � d| �S )zVSend user name, return response (should indicate password required). zUSER %s�r< �r �userr r r rD � s z POP3.userc C s | � d| �S )z�Send password, return response (response includes message count, mailbox size).
