python: smtp/pop/imap

邮件的服务器MTA:smtp协议

邮件的客户端MUA: pop3协议,imap协议。

###############################################

python使用smtplib模块编写邮件服务器程序。

SMTP类:

__init__(self, host=”, port=0, local_hostname=None, timeout=<object object>)

smtplib.SMTP类的方法:

connect(host=’localhost’, port=0)

sendmail(from_addr, to_addrs, msg, mail_options=[], rcpt_options=[]):

to_addrs是一个地址列表,msg的From: To: Subject:能自动识别

sendmail返回没有发出的邮件和错误信息的字典{email,message}

quit()

################################################

python的邮件客户端模块有poplib和imaplib两种

POP3类:

__init__(self, host, port=110, timeout=<object object>)

POP3类的方法:

user(username)

pass_(password)

stat()-> 获取消息的数量和消息总大小,返回(message count, mailbox size)

list(which=None) ->

如果没有给出which返回,,[‘response’, [‘mesg_num octets’, …], octets]

如果给出which只返回response

retr(which)-> 获取which的服务器返回信息、消息的所有行、消息的字节,返回[‘response’, [‘line’, …], octets]

dele(which) -> 删除which,返回response

quit()

response:是一个字符串: +OK …

[‘line’, …]:是一个列表,列表中‘’前面的是服务器返回的消息内容,后面的是邮件正文内容。

并且为之实践了关怀和付出的善举。对于我性情中的易感和怨薄,
