Having read the RFC's for SMTP, I've been led to believe that sending mail is impossible unless one can telnet to the SMTP port of the destination site (usu. 25). How, then, does mail from aol.com "escape"? Mail *seems* to be coming from something like "emout04.mail.aol.com", but I'm unable to telnet to port 25 there. What's up with that? Isn't the ability to access that port necessary for two machines to exchange message texts? And now I'm *really* getting out of my league... When mail is addressed "email@example.com", the mail program must access the DNS to locate the address to telnet to, right? So why does a telnet to aol.com return a "No address associated with name" error? -Simon D. apologies for the foolish statements in the paragraphs above. And now, ObDiggingDeepInTheCobwebsOfMyHistoryHack: ----------------------------------------- Sim Earth might perhaps be one of the few remaining games with that copy proctection Q/A bull stored unprotected in a resource file (this is on a mac, folks). I first located the data ("hidden" in an obscurely named resource) and tried to just delete it. No go. Then, I tried replacing all the answers with "000", but still, no go (some kind of checksum? or just errors from the bytes getting shifted out of order.) Finally, I loaded the data into a text file and printed the bastard out. I eventually went back to the thing much later and, as an excercise, located the breakpoint for the "you got the answer wrong" dialog box (needed to trace back a few jumps to get there) and flipped a "BNE" a "BEQ" in the code. Did I mention that Sim Earth really sucks?
