I'm having a big mailer problem on a Microvax II running Ultrix 3.0. Our binmail (-rwsr-sr-x 1 root mail 62464 Oct 19 1988 /usr/bin/mail) is seemingly randomly screwing up mail. Most of the mail is addressed to aliases on our system, and the error that occurs is "Unknown Mailer Error 255" For example, I have an alias "seclist" on the system which is aliased right now to "aem". (This is where the security digest is addressed to on mthvax). If, as 'daemon', I mail to seclist, I get two maa* files in tmp, with no mail delivery. The first maa* file is simply the mail. The second is what the mailer-daemon attempts to unsuccesfully deliver back. E.g.: Script started on Thu Sep 7 11:13:45 1989 $ whoami daemon $ which mail /usr/ucb/mail $ grep seclist /etc/aliases seclist: aem owner-seclist: aem $ mail seclist Subject: test test Cc: $ mailq Mail Queue (1 request) --QID-- --Size-- -----Q-Time----- ------------Sender/Recipient------------ AA04425* 13 Thu Sep 7 11:14 daemon aem $ mailq Mail queue is empty $ ls /tmp Ex01528 Rx01528 maa4429 maa4433 t3265 typescript $ cat maa4429 From daemon Thu Sep 7 11:14:43 1989 Date: Thu, 7 Sep 89 11:14:39 EDT From: daemon (Mr Background) To: seclist Subject: test test test $ cat maa4433 From daemon Thu Sep 7 11:14:45 1989 Date: Thu, 7 Sep 89 11:14:39 EDT From: MAILER-DAEMON (Mail Delivery Subsystem) Subject: Returned mail: unknown mailer error 255 To: owner-seclist ----- Transcript of session follows ----- 554 aem... unknown mailer error 255 ----- Unsent message follows ----- Received: by mthvax.CS.Miami.EDU (5.57/890828aem) id AA04425; Thu, 7 Sep 89 11:14:39 EDT Date: Thu, 7 Sep 89 11:14:39 EDT From: daemon (Mr Background) To: seclist Subject: test test test $ tail /usr/spool/mqueue/syslog Sep 7 11:14:40 localhost: 4425 sendmail: AA04425: message-id=<8909071514.AA04425@mthvax.CS.Miami.EDU> Sep 7 11:14:40 localhost: 4425 sendmail: AA04425: from=daemon, size=37, class=0 Sep 7 11:14:43 localhost: 4427 sendmail: AA04425: to=aem, delay=00:00:04, stat=unknown mailer error 255 Sep 7 11:14:44 localhost: 4427 sendmail: AA04427: message-id=<8909071514.AA04427@mthvax.CS.Miami.EDU> Sep 7 11:14:44 localhost: 4427 sendmail: AA04427: from=MAILER-DAEMON, size=0, class=0 Sep 7 11:14:46 localhost: 4432 sendmail: AA04427: to=aem, delay=00:00:03, stat=unknown mailer error 255 $ ^D script done on Thu Sep 7 11:15:26 1989 Now, I'm baffled. The mailer is properly set up in sendmail.cf, and everything appears to be equivelent to another microvax here with ultrix 3.0 which works without any problem whatsoever. Anyone experience this?

Let's ask a silly question here: do you have world read permissions turned off on /dev/kmem? I had a similar problem when closing up kmem permissions, and it turns out that Ultrix does some sort of really strange (and broken) locking on mail files... and the locking is load-dependent. If it can't get at /dev/kmem, /bin/mail loses. There's a whole pile of MH commands that have similar problems. -Steve Spoken: Steve Miller Domain: steve@umiacs.umd.edu UUCP: uunet!mimsy!steve Phone: +1-301-454-1808 USPS: UMIACS, Univ. of Maryland, College Park, MD 20742
