Is it possible in iptables to access external ports 25 to send mail to everyone except postfix?

I have a rule.

iptables -A OUTPUT -p tcp -m owner --uid-owner postfix -m tcp --dport 25 -j ACCEPT 
iptables -A OUTPUT -p tcp -m tcp --dport 25 -j DROP

--uid-owner postfix - user running postfix

At the level of iptables in any way.
