The log contains this: Jan 5 10:46:59 suillus postfix/smtp[7947]: 15FEE9CE00: to=<[EMAIL PROTECTED]>, relay=smtp.comcast.net[206.18.177.17]:25, delay=7.1, delays=6.5/0.02/0.42/0.16, dsn=5.0.0, status=bounced (host smtp.comcast.net[206.18.177.17] said: 550 [PERMFAIL] acm.org requires valid sender domain (in reply to RCPT TO command)) I took the suggestions of several other people and still get this result: Joachim Schrod suggested changing the sendmail call to something like this: sendmail -t -v From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: test He also noted that mail uses sendmail -- and in fact, mail works perfectly for the relay on my box. Patrick Shanahan suggested adding this to main.cf: relayhost = smtp.comcast.net followed by postfix reload John Andersen suggested that I didn't need to fiddle with main.cf at all, but could just do the configuration through Yast (Mail Transfer Agent). I took all of those suggestions, but still get the message above in the mail log. So the real problem seems to lie with the sender domain. All this reminds me of an experience I had about a month ago when I had some very strange behavior from Grub and asked for help on this list. Ultimately I discovered that I had a hardware problem with the docking unit I was using for my hard drive, so some disk operations were failing -- just a few. So the weird things I was seeing weren't due to software or Grub misconfiguration at all. This time it's almost certainly not hardware.
