如何在python中过滤gmail imap消息的日期？

Question

I have the following code which signs into gmail via imap, selects the inbox, and searches the mailbox for emails that come from billing@gmail.com

How do I filter the data from gmail so that it returns only messages that have a date of today?

m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(username, password)
m.select('inbox') 
resp, data = m.search(None, '(FROM "billing@gmail.com")')
return data

I'm using the following module:

Answer 1

imaplib is just a simple wrapper around the IMAP protocol which is described in this RFC , the specific part of this you would want to look at is the SEARCH command.

In answer to your question to select all messages in the current mailbox that arrived eg on 19th February 2015 you would perform the query (ON 19-Feb-2015)

Some python code which will format todays date in the correct way to make the query would be:

import time
resp, data = m.search(None, "(ON {0})".format( time.strftime("%d-%b-%Y") ) )

now data will contain a list of message numbers recieved today.

Answer 2

You can use SENTSINCE to get most recent messages

date = (datetime.date.today() - datetime.timedelta(days=2)).strftime("%d-%b-%Y")
typ, messages = m.search(None, '(ALL)', f'(SENTSINCE {date})')

To get only today messages you can use

date = datetime.date.today().strftime("%d-%b-%Y")

Une can as well replace '(ALL)' by '(UNSEEN)' to get only unseen messages
