Re: exim/postfix comparisons

Hello,

I've heard comments from respected frequent posters on this list both
that they use postfix and that debian's decision to have Exim as default
was controversial.

I also lurk on OpenBSD's misc list. OBSD uses sendmail by default
because they have made it secure, it has a BSD license, and it is small
so fits nicely in their base install. They didn't use Postfix because
of licencing issues but I think the license has changed. Many people
who lurk there use postfix on their BSD boxes. They don't use Exim also
because of licensing and there have been some disparaging comments on
the complexity.

hmm I do that too. In fact I'm collecting stuff again after leaving
openBSD at 3.5 to get back on track with my knowledge.

As for a compelling reason to learn sendmail, the only one I can think
of is if you ever want to run a base BSD (I think they all include
sendmail in base). Since sendmail was written as the standards for
email were being standardized, it can do anything and not just what is
current practice. This flexibility makes it very complex; whole (large)
books are written on it. In the past, this complexity has left it open
to security issues which I think have now all been fixed (until the next
time one is found, but then OpenBSD would have to change their
front-page brag). Postfix was written by a security guru (I think the
person who gave us tcp-wrappers) and is flexible enough to do everything
neccessary on a modern network.

I guess I'll add myself to the sendmail people then. Can't be that bad
and I don't plan to spend vast amounts of time on that, only on a as
needed basis :)

If it were me and I only knew postfix, I'd find something else to do
than learn another MTA.

Well sometimes when a client asks you "And why exactly do you use
postfix" you just can't answer "Because it's the only tool I know" :)
