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:

Is this the only thing required?

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 ?
