Hey Jim,
I just happened to be doing this today, so here are my notes on how to
set up postfix to send mail out from a generic server, like for logwatch
output and such (that would otherwise go to r...@localhost).
{replace what's in braces, and remove braces}
# yum install postfix
# yum remove sendmail
# cd /etc/pki/tls/certs
# make postcert.pem
# echo "{submission.server.com}:587 {user:passwd}" \
> /etc/postfix/sasl_passwd
# chmod 600 /etc/postfix/sasl_passwd
# chown root:root /etc/postfix/sasl_passwd
# postmap /etc/postfix/sasl_passwd
Edit /etc/aliases if desired, then do newaliases command:
root: sysadmin
# newaliases
Edit /etc/postfix/main.cf, changing these from the default values (this
was CentOS5.3):
myorigin = $mydomain
#mydestination =
mynetworks_style = host
relayhost = {submission.server.com}:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =
smtp_use_tls = yes
smtp_tls_CAfile = /etc/pki/tls/certs/postcert.pem
smtp_tls_session_cache_database = btree:/var/run/smtp_tls_session/cache
# service postfix start
# chkconfig postfix on
That should do it.
Note, this configuration relies on hostname being set correctly for your
domain. If it's not, you'll need to change the myorigin variable
appropriately.
Please let us know whether or not this works for you.

That's not telling us much. I sure don't know, and don't care to know
sendmail. If you'd try using postfix again we might be of more help. For
what you need, postfix isn't a bad choice. Certainly better than sendmail.

it is centos 4.7 running sendmail ( what came with it ) I started to
install postfix because I am a bit more farmilur with that than send
mail.
Postfix was what i was using before i found -- the best mailserver
solution of qmailtoaster...
anyways
I can email with a client ( evolution ) and that does come through
even though I am using sendmail. the smtp server is one from the isp -
a dsl modem etc.
I can command line send mail ( sendmail ) to a gmail account - but
not mu internal domain
I was wondering about MX or Reverse DNS -
here is the full header of the client ( evolution ) email that does
come through
