POP3 in Python - 4 (Deleting Message)

呼叫POP3Object.dele(msgnum)就可以刪除指定的信件了。

只是大多時候，server會等到呼叫quit()時才正式把信件刪除，

mblist = p.list()[1]
dellist = []

for item in mblist:
    number, octets = item.split(' ')
    log("Downloading message %s (%s bytes)...\n" % (number,octets))
    
    lines = p.retr(number)[1]
    
    msg = email.message_from_string("\n".join(lines))
    
    destfd.write(msg.as_string(unixfrom = 1))
    destfd.write("\n")
    dellist.append(number)

在此先用一個dellist把所有要刪的存入

在這裡進行刪除：

counter = 0

for number in dellist:
    counter += 1
    log("Deleting message %d of %d...\n" % (counter, len(dellist)))
    p.dele(number)

最後呼叫quit()就可以順利刪除了。

來看看程式的output：
