Once upon a time, many years ago, I tried postfix. I ended up removing it and installing sendmail. I've been using sendmail since the early 1980's, when we were running the Eric Allman code from UCB on a VAX 780 under BCD Unix. And, yes, I recognize this as a religious topic and I'm not trying to start a flame war. Why, in your opinion, is postfix superior to sendmail. > > > Harold > (who's first linux system was slackware 1.0) You were probably more comfortable running sendmail because you had a long history of using it. I once tried to give emacs a fair shake, but since I had already used vi for a long time, I didn't like it. I'm honest enough to say that it was mostly because I was comfortable with vi, and not that there's anything wrong with emacs . Conceptually, the fact that sendmail requires a makefile and a bunch of macros just to generate the configuration pretty clearly points to *something* being wrong, or at least anachronistic, with the design. Objectively, it performs all of its tasks within the same process, adding significantly to potential security issues. Postfix uses simple name=value syntax but can still get as complex as you need, if you do. It also segregates functions into different processes, isolating areas that might pose higher security risks. ❧ Brian Mathis  This is just an anecdote. Please for the love of Linus do not reply to the vi vs emacs statement.
