メッセージを削除するimap
メールボックスからメッセージを削除するにはどうすればよいですか？このコードを使用していますが、文字が削除されていません。英語でごめんなさい。
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()
これは、受信トレイ内のすべての電子メールを削除するための作業コードです。
import imaplib
box = imaplib.IMAP4_SSL('imap.mail.microsoftonline.com', 993)
box.login("[email protected]","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()
まず、削除するメールにマークを付ける必要があると思います。例：
for num in data[0].split():
box.store(num, '+FLAGS', '\\Deleted')
box.expunge()
次のコードは、いくつかのメッセージヘッダーフィールドを出力してから、メッセージを削除します。
import imaplib
from email.parser import HeaderParser
m = imaplib.IMAP4_SSL("your_imap_server")
m.login("your_username","your_password")
# get list of mailboxes
list = m.list()
# select which mail box to process
m.select("Inbox")
resp, data = m.uid('search',None, "ALL") # search and return Uids
uids = data[0].split()
mailparser = HeaderParser()
for uid in uids:
resp,data = m.uid('fetch',uid,"(BODY[HEADER])")
msg = mailparser.parsestr(data[0][1])
print (msg['From'],msg['Date'],msg['Subject'])
print m.uid('STORE',uid, '+FLAGS', '(\\Deleted)')
print m.expunge()
m.close() # close the mailbox
m.logout() # logout
GMailを使用している場合、プロセスは少し異なります。
- [Gmail]/Trashフォルダに移動します。
- [Gmail] /ゴミ箱フォルダから削除します（\削除フラグを追加します）
[Gmail]/Spamと[Gmail]/Trashのすべてのメールは30日後に削除されます。 [Gmail]/Spamまたは[Gmail]/Trashからメッセージを削除すると、メッセージは完全に削除されます。
タグDeletedを設定した後、[〜＃〜] expunge [〜＃〜]を呼び出すことも忘れないでください。
これは私にとってはうまくいくものであり、各電子メールを個別に削除（ストア）するのではなく、代わりにリストインデックスを渡すので非常に高速です。これは、Gmailの個人用と企業用（Google Apps for Business）で機能します。最初に、使用するフォルダー/ラベルを選択します。m.list（）は、使用可能なすべてのものを表示します。次に、1年以上前のメールを検索し、ゴミ箱に移動します。次に、ゴミ箱にあるすべての電子メールに削除フラグを付けて、すべてを消去します。
#!/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."
上記のコードに基づいて私が書いたプログラムは次のとおりです。

PyPurge Email V1.0
==================

This Python 3 program will scan an email account using IMAP for messages older than
a certain age and delete them.
Old email can be deleted from all folders or each folder.
Because of the length of time bulikng deleting takes, folders can be scanned first
then the deletions can be left running (which might take several hours for many
thousands of messages.)
After running this, you may need to "empty" your deleted items/Trash folder to recover the space.
With hotmail/live/Outlook accounts (i.e. online Microsoft ones) you will need to manually empty "recoverable items" too.
This is done within the "deleted items" folder when viewing your webmail.
