A client uses hash files for transport and access on a couple relays. When I need to make a change to one of these files I typically just edit it and then do a postmap whatever. On one of the machines it doesn't seem to pickup the change until I restart postfix (it's an older machine with an older version of postfix on it -- which I'm working on the upgrade plan for).
Can someone confirm that we only need to postmap something and not restart the entire subsystem? At least, that's been my understanding for years anyway. Gary
