Getting n most recent emails using IMAP and Python

This is the code to get the emailFrom, emailSubject, emailDate, emailContent etc..

import imaplib, email, os
user = "[email protected]"
password = "pass"
imap_url = "imap.gmail.com"
connection = imaplib.IMAP4_SSL(imap_url)
connection.login(user, password)
result, data = connection.uid('search', None, "ALL")
if result == 'OK':
    for num in data[0].split():
        result, data = connection.uid('fetch', num, '(RFC822)')
        if result == 'OK':
            email_message = email.message_from_bytes(data[0][1])
            print('From:' + email_message['From'])
            print('To:' + email_message['To'])
            print('Date:' + email_message['Date'])
            print('Subject:' + str(email_message['Subject']))
            print('Content:' + str(email_message.get_payload()[0]))
connection.close()
connection.logout()        

# get recent one email
from imap_tools import MailBox
with MailBox('imap.mail.com').login('[email protected]', 'password', 'INBOX') as mailbox:
   for msg in mailbox.fetch(limit=1, reverse=True):
       print(msg.date_str, msg.subject)

The sort command is available, but it is not guaranteed to be supported by the IMAP server. For example, Gmail does not support the SORT command.

To try the sort command, you would replace:
M.search(None, 'ALL')
with
M.sort(search_critera, 'UTF-8', 'ALL')

Then search_criteria would be a string like:

search_criteria = 'DATE' #Ascending, most recent email last
search_criteria = 'REVERSE DATE' #Descending, most recent email first

search_criteria = '[REVERSE] sort-key' #format for sorting

According to RFC5256 these are valid sort-key's:
"ARRIVAL" / "CC" / "DATE" / "FROM" / "SIZE" / "SUBJECT" / "TO"

Notes:
1. charset is required, try US-ASCII or UTF-8 all others are not required to be supported by the IMAP server
2. search critera is also required. The ALL command is a valid one, but there are many. See more at http://www.networksorcery.com/enp/rfc/rfc3501.txt

The world of IMAP is wild and crazy. Good luck
