Postfix ignoring one of the manually applied changes

[wrobelda]

Hi,

I need to set local_header_rewrite_clients = permit_mynetworks in postfix configuration, so I added it to  /usr/local/etc/postfix/main.cf accordingly, restart the service, yet the old, default permit_inet_interfaces value persists, confirmed by postconf -d , as well as the actual behavior of postfix in that aspect.

For the record, I applied other options the same way and they work just fine, so postfix doesn't like this particular one for some reason. I searched the Internet and couldn't find anything specific to postfix itself that would make it ignore that switch, hence I wonder if this is some OPNSense or FreeBSD peculiarity that I am missing?

Any ideas?
