I am trying to set up sendmail 8.11.0 (don't ask me why - I just want to). I have it installed, I have the /etc/mail/sendmail.cf setup via the generic-linux.mc file. I am trying to start sendmail in this way : "/usr/sbin/sendmail -bd -q30m" No problem it starts. I can send mail from the local to computer to any other machine on the net. However, when I send mail to my machine from elsewhere, or when I send local mail on my machine - it never arrives. I look at the queue (sendmail -bp) and it shows two entries in the queue. I have tried to force queue processing (sendmail -v -q) and I am getting the following errors: [root at cascade cf]# sendmail -v -q Running /var/spool/mqueue/e7O0bRn27703 (sequence 1 of 2) <root at cascade.veldy.net>... Connecting to local... <root at cascade.veldy.net>... Operating system error Running /var/spool/mqueue/e7NKQf427623 (sequence 2 of 2) <veldy at cascade.veldy.net>... Connecting to local... <veldy at cascade.veldy.net>... Operating system error Currently, it is running under the root user (right now it is a test box and behind a firewall). I believe all permissions are correct. Incidentally, I followed all the instructions in the README and INSTALL files throughout the distributions (yuck!) to set up sendmail from source. I originally got the following error when starting sendmail: /etc/mail/sendmail.cf: line 63: fileclass: cannot open '/etc/mail/local-host-names': No such file or directory I created a file called /etc/mail/local-host-names with the following: cascade.veldy.net localhost I tried many combinations of this to no effect. I have the latest bind installed on this machine also, but it is not running. I am using DNS services on another host. Any help getting through this would be greatly appreciated.
