>From my server installation notes:-

sudo aptitude install -r postfix
Select "internet with smarthost" option
then enter the relay server address to be used with SASL
Read the MailRelaySetup and SMTPAuthWithSASL to complete the
installation.

Then edit a couple of main.cf lines:-

mydestination = thefletchers.net, $myhostname, ServerIV,
localhost.localdomain, localhost

mynetworks = 192.168.2.0/24 localhost

Should get it working locally and receiving email from the Internet, if
you've got a domain and you've set your MX record to get to your
server, and set up your aliases file. If you want it to relay out via
someone else's SMTP server you'll likely have to do the SASL stuff too.

I tried years ago to get sendmail to work for me and gave up on it.
