Craig, I stopped qmail, which I had installed outside of yum, turning off sendmail first, then I just did a yum install postfix and (I believe) /etc/init.d/postfix start or some such and it's sending email. All well, or should I do a yum remove postfix and then your commands?

TIA,
Suzie

No but you need to do this then...

chkconfig postfix on
chkconfig sendmail off

and if there is some mechanism for starting qmail on startup, you will
have to disable it...perhaps there is a sysv initscript that you can
discover here...

chkconfig --list

See my slightly prior post on: Re: [CentOS]
smtp+pop3+imap+tls+webmail+anti spam+anti virus

It points you to:
http://howtoforge.net/virtual-users-domains-postfix-courier-mysql-squirrelmail-fedora-10

Now granted this is for FC10, but I suspect it would be easy to fit into
Centos.

Also the patch to Postfix is for quota support. If you don't need
quotas, you canprobably skip that part.

qmail usually uses daemon-tools. check supervise man page.

but then what ISN'T simpler to configure than sendmail?

Please, for the love of god and country, do not follow garbage
like this. Under "1. Preliminary Note" is this text:

"You should make sure that the firewall is off (at least for
now) and that SELinux is disabled (this is important!)".

Documents that advocate disabling SELinux should be tossed
in a pile and set on fire. Documents that tell you to
disable your firewall with no mention in the remaining
portion of the document to reenable it post install or
how to properly configure it should join the burn pile.

Howtoforge, while perhaps useful for *something* at *some*
point in time, more often than not provides information
which will either break your system outright or lead to
tears and suffering before bedtime.

Hardly anything, given that it is almost completely done for you in the
supplied /etc/mail/sendmail.mc file. You just have to fix the
intentionally-borked DAEMON_OPTIONS if you want to receive outside mail,
fill in SMART_HOST if you'd like another machine to relay for you, and
add entries in the access file for networks you want to relay for. And
restarting the sendmail service will do the updates you need after
changing these files.

Beyond that, you'd probably want to add a milter like MimeDefang so you
can do anything complex and non-standard in perl.

This reminds me of the Woody Allen movie where they asked the couple,
how often they had sex and the man said, "hardly ever, maybe only twice
a week" and the woman said "it seems like all of the time...maybe twice
a week"
