sendmail or postfix

Hi all,

I've got a big decision to make and I need a good solution.

I have to setup a mail server with 6 virtual domains with 100 users
approx. each.

Each domain needs to have it's own IP address.

I want to control spam with spam assasins.

For now, I'm using sendmail on Red Hat 7.3 and Linuxconf to configure
sendmail. It works great but I have no control over SPAM. Linuxconf is
a great tool when your not to experience with sendmail, but it is
unstable and not recommended for sendmail. Luckily I've never had
problem with it yet. But now I need to add two more virtual servers
and control spam. Linuxconf is no longer available, and I want to use
Fedora Core-3.

What mail server should I use: Sendmail or Postfix

Sendmail seems very complex and I don't know anything about Postfix.

Does Postfix can use virtual domains with different ip addresses?

Thanks, in advance, for your help.

Not for the MX record, you can point them to same system if you
like.

Good idea, with a little work in setting SA up, you can sort out
or tag nearly 100% of the crap. Make sure you run the latest
version and upgrade on a regular basis, a key factor to keep spam
out.

You could try out webmin for configuring sendmail, if you prefer
something more GUI based. Never used linuxconf, didn't even knew
it came with RH 7.3, but heard only bad things about it.

I'd suggest to look into the enterprise version or one of the
free clones (CentOS and alike), simply because the availability of
patches for 5-7 years. In addition with a real enterprise version
you get some support and can always blame RH, if something goes
wrong and open a ticket, you have to know if this is worth the
few bucks/year.

Hard to tell, personally prefer sendmail, it's not that hard
configuring on linux with help of m4 and a little reading the
docs. But then, your mileage might be different.

From a short view sendmail + spamassassin can be configured from
webmin (http://www.webmin.com/) through your favorite www
browser, it supports in addition configuring qmail which you
should take a serious look at as sendmail alternative.

Good luck

OK.

Why ? You can run several (virtual) domains on the same IP.

Good.

RedHat 7.3 is way too old, FC3 (me think FC4 is around the corner) is
probably a better choice. You could use Webmin to configure your servers
(through a web browser).

Personally I use Sendmail, but I've heard Postfix is better integrated
with SpamAssassins.

For configuration, use Webmin (for sendmail or postfix) and Maia for spam.

Sendmails .mc file is not that complicated, I don't know about Postfix.

I think so, but check the documentation.

There're several good tutorials for setting up mail servers using
Postfix, Amavisd, ClamAV, and SpamAssassin.
I'm using this setup for my gateway machine:

Works really well, so far.

Thank you all,
I'm trying this config: Postfix with Mysql, Cyrus-sasl, postfix-admin.
dovecot and SA.

I'll let you know how it turn out

thank!
