You are so right!
I cannot see why you would use anything other than a firewall to do
what you want.
Why complicate your postfix configuration files? make one more thing to
remember in an upgrade or disaster recovery?
I can't tell you what to do with your firewall specifically because I
don't know what your OS/firewall details are. Logically it looks like:
Block in all ( a default rule hopefully)
Pass in on $external_interface from <table of IPs of your filter
company> to $mailserverIP port smtp
All traffic from outside to port 25 blocked except from filtering
Nothing hard about that.

On-list replies only (if any) please. Desperate off-list replies to the
reply-to address only.
A consultant is someone who's called in when someone has painted himself into a corner. He's expected to levitate his client out of that corner.
