I am interested to trigger a certain action upon receiving an email from specific
address with specific subject. In order to be able to do so I need to implement
monitoring of my mailbox, checking every incoming mail (in particular, i use gmail).
what is the easiest way to do that?
Gmail provides the ability to connect over POP, which you can turn on in the gmail settings panel. Python can make connections over POP pretty easily:
import poplib from email import parser pop_conn = poplib.POP3_SSL('pop.gmail.com') pop_conn.user('username') pop_conn.pass_('password') #Get messages from server: messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()) + 1)] # Concat message pieces: messages = ["\n".join(mssg) for mssg in messages] #Parse message intom an email object: messages = [parser.Parser().parsestr(mssg) for mssg in messages] for message in messages: print message['subject'] pop_conn.quit()
You would just need to run this script as a cron job. Not sure what platform you're on so YMMV as to how that's done.
