It is possible to:
 - start the reactor when I initialize my program (eg. in main)
 - call connectTCP or connectSSL when I want and every time I want?

Something like this:

def check_messages(account):
	# connect to imap server and check for new mailboxes/messages
	reactor.connectSSL(...)


if __name__ == "__main__":
	reactor.run()

	check_message(account1)
	check_message(account2)
	...
	do something else
	...
	check_message(accountn)


Because I can't implement this :}

I have started the implementation based on "Twisted Network Programming 
Essential", but this book doesn't treat multiple connections...
