郵件的伺服器MTA:smtp協定
郵件的用戶端MUA: pop3協定,imap協定。
###############################################
python使用smtplib子產品編寫郵件伺服器程式。
SMTP類:
__init__(self, host='', port=0, local_hostname=None, timeout=<object object>)
smtplib.SMTP類的方法:
connect(host='localhost', port=0)
sendmail(from_addr, to_addrs, msg, mail_options=[], rcpt_options=[]):
to_addrs是一個位址清單,msg的From: To: Subject:能自動識别
sendmail傳回沒有發出的郵件和錯誤資訊的字典{email,message}
quit()
################################################
python的郵件用戶端子產品有poplib和imaplib兩種
POP3類:
__init__(self, host, port=110, timeout=<object object>)
POP3類的方法:
user(username)
pass_(password)
stat()-> 擷取消息的數量和消息總大小,傳回(message count, mailbox size)
list(which=None) ->
如果沒有給出which傳回,['response', ['mesg_num octets', ...], octets]
如果給出which隻傳回response
retr(which)-> 擷取which的伺服器傳回資訊、消息的所有行、消息的位元組,傳回['response', ['line', ...], octets]
dele(which) -> 删除which,傳回response
quit()
response:是一個字元串: +OK ...
['line', ...]:是一個清單,清單中‘’前面的是伺服器傳回的消息内容,後面的是郵件正文内容。
