I did:-

yum install exim
yum erase (or was it remove?) sendmail

Never used postfix. For mail I use Evolution 2.12.3 (2.12.3-19.el5). If
I want to route outgoing mail by the Exim on the machine I'm using I
just quote the mail server's host name (example. m4.u226.com). Obviously
the Exim, or in your instance Postfix, needs to be configured to accept
locally originating mail

My Exim examples:-

daemon_smtp_ports  = 25 : 55525
local_interfaces   = 127.0.0.1 : 10.123.123.42 (the IP address of the
machine)

Running your own mail server(s) generally means you simply send direct
and your emails are not delayed by problems at your ISP.
