[BlueOnyx:26817] Firewall question

[Brian Davis]

Recently upgraded and before always used iptables.  As such not very
familiar with firewalld. 

I usually don't allow incoming connections on port 25 (localhost only)
but allow outgoing connections on port 25. 

What is a good way to implement this?  I am used to using iptables with
the following: 

iptables -A INPUT -p tcp -s localhost --dport 25 -j ACCEPT
iptables -A INPUT -p tcp --dport 25 -j REJECT 

Any help would be appreciated.
