How odd! How is that client connecting to your system? I.e. is it via their ADSL then in to yours, or is your postfix server 'out there' somwhere and thus not behind a NAT router? Does the non-local IP make any sense at either their end or your end?
It's a straight connection via their ADSL to a server "out there" and not behind any kind of NAT that I know of, and the IP address is random and does not match that of her desktop. It only affects this one client.
My first suspicion would fall on her ADSL connection/router then, i.e. the router's NAT is throwing a wobbly of some sort and putting a private IP address out.
Is there any chance you can get her to use a different router?
Should we take this off list?
Maybe, but not yet, I think.
OK
