SMTP is used to transmit e-mail messages to mail servers. Python provides the smtplib module for SMTP clients to use. By calling the sendmail() method of SMTP objects, you can transmit messages. The sole way of specifying the actual recipients of a message is with parameters to sendmail(); the To, Cc, and Bcc message headers are separate from the actual list of recipients. Several different exceptions could be raised during an SMTP conversation. Interactive programs should check for and handle them appropriately. ESMTP is an extension to SMTP. It lets you discover the maximum message size supported by a remote SMTP server prior to transmitting a message. ESMTP also permits TLS, which is a way to encrypt your conversation with a remote server. Fundamentals of TLS are covered in 6. Some SMTP servers require authentication. You can authenticate with the login() method. SMTP does not provide functions for downloading messages from a mailbox to your own computer. To accomplish that, you will need the protocols discussed in the next two chapters. POP, discussed in 14, is a simple way to download messages. IMAP, discussed in 15, is a more capable and powerful protocol.

Before you begin looking at some basic SQL statements, you should understand that SQL is another programming language. This book will not teach you to develop using SQL; it will show you only the very basic information. You also need to know that the different database servers supported by Qt support different dialects of SQL. This means that a statement can look slightly different for a MySQL connection when compared with an SQLite connection. By sticking to the very basics, these disparities can be avoided, but be prepared to read up on the database engine you choose to use in the SQL manuals. The statements used and described in this section have been tested with both MySQL and SQLite, so there will be no dialectal hiccups.

POP, the Post Office Protocol, is a simple protocol that is used to download e-mail from a mail server, and is typically used through an e-mail client like Thunderbird or Outlook You can read the first few sections of 13 if you want the big picture of where e-mail clients, and protocols like POP, fit into the history of Internet mail The most common implementation of POP is version 3, and is commonly referred to as POP3 Because version 3 is so dominant, the terms POP and POP3 are practically interchangeable today POP s chief benefit and also its biggest weakness is its simplicity If you simply need to access a remote mailbox, download any new mail that has appeared, and maybe delete the mail after the download, then POP will be perfect for you You will be able to accomplish this task quickly, and without complex code.

Open the MyBlocks folder, and double-click the TechnoratiBlockDescription.xml file to open it in the editor. Select all the XML, and copy and paste it into the Block Description editor in the Block Creator. Repeat the same steps for the TechnoratiBlock.js JavaScript code, but paste the code in the Block Code editor. Now, you should have both the description XML and the JavaScript code in the Block Creator. Click the Save button at the top-left corner of the Block Creator window (see Figure 10-9).

The rest of this chapter discusses relational databases, which are collections of tables. The tables each have a name and a set of columns and rows. The columns define the structure of

However, this whole scheme has important limitations POP does not support multiple mailboxes on the remote side, nor does it provide any reliable, persistent message identification This means that you cannot use POP as a protocol for mail synchronization, where you leave the original of each e-mail message on the server while making a copy to read locally, because when you return to the server later you cannot easily tell which messages you have already downloaded If you need this feature, you should check out IMAP, which is covered in 15 The Python Standard Library provides the poplib module, which provides a convenient interface for using POP In this chapter, you will learn how to use poplib to connect to a POP server, gather summary information about a mailbox, download messages, and delete the originals from the server.

the table, while the rows contain the data The tables are then tied together through relations, in which column values from different tables are linked to each other Each column has a name and a type, which make it possible to control what goes where and to retrieve by name You can also control the allowed contents so that a NULL value will be replaced by a default, or you can disallow NULL values altogether The rows contain the data as defined by the columns When you are working with a database you usually search for rows, add them, update them, or remove them The first thing you need to do is create an actual database, and the way you create it depends on the database server that you plan to use Please refer to the user manual of your server for details.
