Connecting to an IMAP server is achieved as follows: import imaplib host = "" port = 143 ssl = 0 try: if ssl: imap = imaplib.IMAP4_SSL(host, port) else: imap = imaplib.IMAP4(host, port) welcomeMsg = imap.welcome print "IMAP Banner: %s" %(welcomeMsg) except: print "Connection Failed" quit() This results in the following output: “IMAP Banner: * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.
