Hello, I just installed Fedora, and installed Big Brother for network monitoring. This is my first time setting up linux, so sorry for a newbie question. I need the server to have SMTP running, so that users in our network can send e-mails to the server, which will fire off a script to deal with the e-mail. For example an admin wants to acknowledge an alert, he sends mail to bb@xxxxxxxxxxxxxxxxxxxxxxxx Initially SMTP wasn't running on my box. So I just ran /etc/rc3.d/S80sendmail start. Okay now sendmail appears to be running. ps -aef | grep sendmail shows root 1725 1 0 Oct25 ? 00:00:00 sendmail: accepting connections smmsp 1734 1 0 Oct25 ? 00:00:00 sendmail: Queue runner@01:00:00 for /var/spool/clientmqueue But if I telnet to port 25 on my system, I get connection refused. There is no firewall. I assume I need to change something in my sendmail config? I read the Red Hat Linux Reference Guide and I couldn't really figure out what I need to change. I was a little concerned about this section: dnl # dnl # The following causes sendmail to only listen on the IPv4 loopback address dnl # 127.0.0.1 and not on any other network devices. Remove the loopback dnl # address restriction to accept email from the internet or intranet. dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl But I'm not sure if I should comment that out. Also I tried to build a new sendmail.cf file and got this error: m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf /etc/mail/sendmail.mc:10: m4: Cannot open /usr/share/sendmail-cf/m4/cf.m4: No such file or directory So I guess I need help with what I have to modify to get sendmail running? And if I need to modify sendmail.mc, then I need help with how to build sendmail.cf? Note - this system will be on the intranet. Not internet accessible. Thanks, Shane
