Eudora apparently sends the IP address of the computer in the URL for Google searches from within the mail program in the latest Windows version. This raises the question of what URL might be included if, for example, Eudora is operated behind a firewall - and suddenly internal information is sent out.
Apart from that: what's the point? The public IP address of the accessing computer is recognizable to the web server anyway. Somehow it all seems a bit strange.
Well, I was never really convinced by Eudora. The user interface is simply poor. And somehow the program always gave the impression of being half-finished. As if someone had started but lost the thread halfway through.
