class Mail():
    def __init__(self):
        self.user= 'USER'
        self.password= 'PASS'
        self.ser = serial.Serial('/dev/tty.usbmodem621', 9600)
        self.M = imaplib.IMAP4_SSL('imap.gmail.com', '993')
        self.M.login(self.user, self.password)
        
    def checkMail(self):
        self.M.select()
        self.unRead = self.M.search(None, 'UnSeen')

    def sendData(self):
        self.numMessages= self.checkMail()
        #turn the string into packed binary data to send int
        self.ser.write(struct.pack('B', self.numMessages))

Hello Budy
I want to check email subject and IF subject is "Database Moved" then script has to send send to Arduino over serial.
How can I do that?
What is correct code?
Can you help me please

hi, i found their is a idle method that can notify you with callback when new mail comes, but when i try to use it with imaplib and imaplib2, it doesn't work

@csrgxtu could you please share the details about writing the callback way you tried

Hi, Could you please help me to write the python code to receive a call when an email received.
