To enable port 587, edit the file /etc/postfix/master.cf
and remove the # in front of the line:
#submission inet n - n - - smtpd
so that it looks like this:
submission inet n - n - - smtpd
and restart postfix:
service postfix restart
for SASL authentication:

First of all thanks for your post it was the first pas to enable it, but I had to update the IPTables rules to open the port too.
Thanks!!

Sorry for my late answer.
For the users that don't know how to modify iptables I done editing /etc/sysconfig/iptables.
In this case I added this line above the COMMIT line and the REJECTS that I have:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 587 -j ACCEPT
I hope this help someone.

I know this a old post but has been configured on the latest version of today ?
the version is 3.0.2.6
enabling the tls won't cause emails to be rejected or not deleverd for some mail servers ?
