	I've been using linux for e-mail for 6 years and settled on the
use of sendmail, proctor and pine as THE simply best e-mail system ever
devised. If you look this message started on cannac.ampr.org which is
this computer. Cool...

No.

Speaking as a programmer who is NOT a sysadmin, I found both sendmail
and smail completely unusable (read: after trying for months, I still
couldn't get either one to work).  Fortunately, exim and postfix are
both simple and easy to use, maintain, and configure.

Sendmail may be a good choice (this is debatable) if you're setting up
a network for hundreds of users.  For one home user (or even three or
four like me), it's grotesque overkill.  It's like using apache on
your home system (another package I avoid like the plague).  Basically,
a complete waste of resources.

I recently saw someone on the list talk about how much easier the new
sendmail was to configure.  The example looked like some obscure,
baroque mess that only a professional sysadmin could love.  Some
people have no sense of perspective.  Stick with exim or postfix is my
advice.  :-)

If you want to do standard things, sendmail needn't be that difficult to set 
up. Smail is easier, and better suited (at least in my limited experience, 
not being either a professional programmer nor sysadmin, but playing with my 
own box for some years) for uucp when you have some other host that is your 
'smart' host (i.e., it does the dirty work for you). 

If one uses fetchmail, then perhaps sendmail is somewhat overkill, but it 
works OK for plain local mail delivery. Over here, I have it set up to accept 
mail for two different domains (belvedere.sbay.org as well as 
belvdere.vip.best.com) even though 99% of my stuff these days comes through 
fetchmail.

Probably. Other mailers (which I haven't tried, besides smail) may use fewer 
resources. Usually, you need a separate sendmail process for each piece of 
mail going through the system, so if you have hundreds of users sending mail, 
conceivably you might have many simultaneous sendmail processes running at 
any one time. Since Linux shares memory, this doesn't have a whole lot of 
impact, but it does have some, of course.

I have apache running by default here. It's more or less set up, but there's 
little if any content - it's basically what you get when you set Redhat up 
out of the box. Redhat is more agressive with httpd than are other 
distributions probably -- it starts up six or eight separate httpd processes 
on boot. Again, using shared memory, they don't impact quite that much, and 
don't really consume much resources. On my system, these are some of the 
first processes to be swapped out, since they are used very little.
Sure, I could save some resources by not having httpd loaded.

Most of sendmail.cf is a baroque mess. Especially, stuff like rewriting 
rules. But the first part of the file is not all that difficult to figure 
out, although it helps to have a good starting point, such as an example 
working sendmail.cf you can then tweak. Plus, many if not most of the 
sendmail.cf options have comments, so you don't have to know what Dw or 
whatever means -- you just read what the comment says it means and see what 
it is already set to.

Last I configured smail, though, it had about six lines to configure. Not too 
terribly difficult. But you lose (perhaps; I haven't checked out newer 
versions) the ability to do things like reject mail from spammers, although 
that really makes more sense if you get your mail SMTP directly to you and 
not POP, like most people do.

As Derek already pointed out, you really shouldn't have to muck with
/etc/sendmail.cf anymore. Virtually everything can be configured via
m4 macros now.

Granted, it's not the easiest thing in the world the first time, but
after you've done it once it takes little effort.
