imap - 如何删除邮件

Question

我该怎么从邮箱里删除消息呢？我用这个代码，但信件没有被删除。抱歉我的英语不好。

def getimap(self,server,port,login,password):
    import imaplib, email
    box = imaplib.IMAP4(server,port)
    box.login(login,password)
    box.select()
    box.expunge()
    typ, data = box.search(None, 'ALL')
    for num in data[0].split() :
        typ, data = box.fetch(num, '(UID BODY[TEXT])')
        print num
        print data[0][1]
    box.close()
    box.logout()

Answer 1

这是我用的方法，速度非常快，因为我不是一个个删除邮件，而是直接传递邮件的列表索引。这个方法适用于个人的Gmail和企业版的Gmail（Google Apps for Business）。首先，它会选择要使用的文件夹或标签，使用m.list()可以查看所有可用的选项。接着，它会搜索一年前的邮件，然后将这些邮件移动到垃圾箱。最后，它会给垃圾箱里的所有邮件加上删除标记，并彻底清除所有内容：

#!/bin/python

import datetime
import imaplib

m = imaplib.IMAP4_SSL("imap.gmail.com")  # server to connect to
print "Connecting to mailbox..."
m.login('gmail@your_gmail.com', 'your_password')

print m.select('[Gmail]/All Mail')  # required to perform search, m.list() for all lables, '[Gmail]/Sent Mail'
before_date = (datetime.date.today() - datetime.timedelta(365)).strftime("%d-%b-%Y")  # date string, 04-Jan-2013
typ, data = m.search(None, '(BEFORE {0})'.format(before_date))  # search pointer for msgs before before_date

if data != ['']:  # if not empty list means messages exist
    no_msgs = data[0].split()[-1]  # last msg id in the list
    print "To be removed:\t", no_msgs, "messages found with date before", before_date
    m.store("1:{0}".format(no_msgs), '+X-GM-LABELS', '\\Trash')  # move to trash
    print "Deleted {0} messages. Closing connection & logging out.".format(no_msgs)
else:
    print "Nothing to remove."

#This block empties trash, remove if you want to keep, Gmail auto purges trash after 30 days.
print("Emptying Trash & Expunge...")
m.select('[Gmail]/Trash')  # select all trash
m.store("1:*", '+FLAGS', '\\Deleted')  #Flag all Trash as Deleted
m.expunge()  # not need if auto-expunge enabled

print("Done. Closing connection & logging out.")
m.close()
m.logout()
print "All Done."

我觉得你应该先把要删除的邮件标记出来，比如：

for num in data[0].split():
   box.store(num, '+FLAGS', '\\Deleted')
box.expunge()

这是一个可以用来删除你收件箱里所有邮件的有效代码：

import imaplib
box = imaplib.IMAP4_SSL('imap.mail.microsoftonline.com', 993)
box.login("user@domain.com","paswword")
box.select('Inbox')
typ, data = box.search(None, 'ALL')
for num in data[0].split():
   box.store(num, '+FLAGS', '\\Deleted')
box.expunge()
box.close()
box.logout()
