Need help setting up smart host for RHEL5
Posted on 2010-09-16
Fresh install of RedHat Enterprise Linux 5.
On a scale of 1 to 10 my skill level with linux is about a 3, please take this into account when replying.
I have an Exchange 2007 server I'd like this redhat box to forward all mail to. The mail coming from this system will just be internal email from the system and Nagios. No outside mail will be hitting this box. I just want to be able to get the alerts via email. I'm assuming this is the easiest way.
I've modified my /etc/mail/sendmail.mc file to define the exchange server.
dnl # Uncomment and edit the following line if your outgoing mail needs to
dnl # be sent out through an external mail server:
The RHEL box can ping the exchange box via FQDN. The next steps I followed from another EE question I found but they didn't work on my system.
Here it is.
[root@Tank mail]# make
WARNING: 'sendmail.mc' is modified. Please install package sendmail-cf to update your configuration.
[root@Tank mail]# 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 that's where I am, what do i need to do next to make this all proper and have the rehat box send me alerts, either directly or via a smarthost?
