exchange mail only with trusted servers, then lack of authentication is clearly a problem warranting an error message; but for a general-purpose client, it probably merits a warning instead. Listing 13 5 acts as a TLS-capable general-purpose client. It will connect to a server and use TLS if it can; otherwise, it will fall back and send the message as usual. (But it will die with an error if the attempt to start TLS fails while talking to an ostensibly capable server!) Listing 13 5. Using TLS Opportunistically #!/usr/bin/env python # SMTP transmission with TLS - 13 - tls.py import sys, smtplib, socket if len(sys.argv) < 4: print "Syntax: %s server fromaddr toaddr [toaddr...]" % sys.argv[0] sys.exit(2) server, fromaddr, toaddrs = sys.argv[1], sys.argv[2], sys.argv[3:] message = """To: %s From: %s Subject: Test Message from simple.py Hello, This is a test message sent to you from the tls.py program in Foundations of Python Network Programming.

You can use the scroll bar to see all of the available objects and functions. Select the environment object from the list and press Tab. The word environment should be added to the editor. Type a period after the word environment, and another drop-down menu will appear showing the available properties and operations of the Popfly environment object (see Figure 10-6). You should remember the important getXml function, which allows you to retrieve XML data from web service, from our code in s 7, 8, and 9. Select getXml to insert it into the editor.

When threading, you must ensure that QObject instances are kept to a single thread. You can access members of a QObject from a thread other than the thread in which the object was created. Just make sure to protect any shared data. Some QObject derivates are not meant for sharing at all: the networking classes, the entire database module, and the QProcess class. Graphical classes are even pickier they must be used from the main thread.

else: print "Message successfully sent to %d recipient(s)" % len(toaddrs) If you run this program and give it a server that understands TLS, the output will look like this: $ ./tls.py localhost jgoerzen@complete.org jgoerzen@complete.org Negotiating TLS.... Using TLS connection. Message successfully sent to 1 recipient(s) Notice that the call to sendmail() in these last few listings is the same, regardless of whether TLS is used. Once TLS is started, the system hides that layer of complexity from you, so you do not need to worry about it. Please note that this TLS example is not fully secure, because it does not perform certificate validation; again, see 6 for details.
