In this book you'll learn the technology underlying secure e-mail systems, from the protocols involved to the open source software packages used to implement e-mail security. This book explains the secure MIME (S/MIME) protocol and how it is used to protect data transmitted across the Internet. It also explains the concepts crucial to stopping spam messages using the three most popular open source mail packages--sendmail, qmail, and postfix. It presents detailed configurations showing how to avoid accepting messages from known open relays and how to filter known spam messages. Advanced security topics are also covered, such as how to install and implement virus scanning software on the mail server, how to use SMTP authentication software, and how to use the SSL protocol to secure POP, IMAP, and WebMail servers.

Addressing everyone who uses email, the authors demystify viruses and spam, explaining how spammers gain access to email addresses, how they trick users into opening messages, and how spammers can use corporate email servers as a front for their unwanted messages. Includes practical advice for administrators setting policy and installing filters to block spam, as well as tips to help users avoid becoming part of the problem.

Email hub - The term Mail Hub is used to denote an MTA or system of MTAs used to route email but not act as a mail server (having no end-user email store) since there is no MUA access. Examples could include dedicated anti-SPAM appliances, anti-virus engines running on dedicated hardware, email gateways and so forth.

Mail filter - A mail filter is a piece of software which takes an input of an e-mail message. For its output, it might pass the message through unchanged for delivery to the user's mailbox, it might redirect the message for delivery elsewhere, or it might even throw the message away.
