Anyone want to drop clues on a Unix newbie? I used it briefly many many years ago, and hated it then, and since then have only used it within the context of MUDs. I've been trying to work through the Terminal tutorial at MacDevCenter, and ran into a problem. It gives directions for setting up sendmail, but the file it mentions, sendmail.cf, doesn't seem to exist on my machine, at least not that I can find. It's got a man page for sendmail, but that seems to be all. It does have seem to have Postfix, and when I try to send mail, it seems to work, but it doesn't actually send. I get Oct 30 22:24:04 mirabelle postfix/local: 026254DABA: to=<Sabrah@mirabelle.local>, relay=local, delay=0, status=bounced (unknown user: "sabrah") and Oct 30 22:27:59 mirabelle postfix/smtp: 048454DACC: to=<email@example.com>, relay=his.com.s5a1.psmtp.com[18.104.22.168], delay=19, status=bounced (host his.com.s5a1.psmtp.com[22.214.171.124] said: 553 5.1.8 <Sabrah@mirabelle.local>... Domain of sender address Sabrah@mirabelle.local does not exist - on relay of: MAIL FROM:<Sabrah@mirabelle.local> (in reply to RCPT TO command)) The latter actually makes sense; I wasn't expecting HIS to accept it anyway. But what's going on with the former? Why would it let me send the mail without an error message if it thinks I don't exist? How can I make this work? And -- would it be possible to set it up so that I can send to/from my regular HIS account? For instance, if I wanted Mirabelle to send alert messages to my regular account when I'm out of town and checking my HIS mail via web cafes or whatnot. A couple other differences with that tutorial: + It's talking about tcsh, but I seem to be using bash. + It has a % after the username, where I have a $. The tutorial was written for Jaguar, and I'm using Panther, so I assume that explains some of the differences. But what do the differences mean? Finally, is there a way to make it stop showing the username with the prompt, and to change the prompt to something more interesting than the computer name?
