You either love it for being so versatile and ubiquitous, or you hate it for being bloated, complicated and insecure. Or perhaps you're a complete newcomer to the e-mail server game and would like to give sendmail a try (after all, sendmail is arguably the most popular open-source software package on the Internet). Well, contrary to popular belief, sendmail isn't a total loss where security is concerned, nor does it require learning the arcane syntax of sendmail.cf (although hardcore sendmail gurus do indeed master it). This month we examine these and other sendmail security controversies, using sendmail's handy m4 macros to rapidly build a secure but functional Simple Mail Transport Protocol (SMTP) gateway to handle internet mail.

This article is intended to bring you up to speed quickly on how to use postfix on your network as a secure means of receiving e-mail from and delivering it to Internet hosts. In particular we'll focus on deploying postfix on firewalls, in DMZs and in other settings in which it will be exposed to contact with untrusted systems. Wietse Venema, intrepid developer of TCP wrappers and co-creator of SATAN, has come through for us again: his program, postfix, provides an alternative to sendmail that is simpler in design, more modular, easier to configure and less work to administer. Equally important, it's been designed with scalability, reliability and sound security as fundamental requirements. The link for this article located at Linux Journal is no longer available. .
