Interesting article. I can't get the mail command to work, though. Running 10.2.6, I used the "sudo chmod g-w /" command to try & get sendmail running.
Entries in mail.log show this error:
Aug 20 08:40:37 Powerbook sendmail: h7KDebKA001530: from=pat, size=28, class=0, nrcpts=1, msgid=<200308201340.h7KDebKA001530@powerbook.local>, relay=pat@localhost
Aug 20 08:40:42 Powerbook sendmail: h7KDebKA001530: to=pat, ctladdr=pat (501/20), delay=00:00:05, xdelay=00:00:05, mailer=relay, pri=30023, relay=localhost.local. [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by localhost.local.
Any help would be appreciated.
