Sending up SMTP Relay and Aliases on the Oracle Database Appliance

The Oracle Database Appliance is a set of 2 Linux servers. so most of the activities that take place out sode of the database are standard Linux activities. One of the things i found out as i was trying to look at things was getting all the unix mail from root and other accounts to our own email addresses. This can be done by setting up and smtp relay. The Oracle Database Appliance needs sendmail-cf  package installed. This can be installed by setting up the Oracle Public yum repository
After installing the sendmail-cf package. the process of setting up a relay to your corporate mail host is pretty simple.
1. Add or modify  in /etc/mail/   define(`SMART_HOST', `your-smtp-server')
2. Shutdown down sendmail service by issuing /sbin/service sendmail stop 
3.  Issue  "m4 /etc/mail/ > /etc/mail/"
4. Startup Sendmail Service /sbin/service sendmail start 

This will setup a non Authenticated sendmail relay for messages to go out of your box.
To Setup Aliases you need to go thru the following
1. edit the /etc/aliases
2. Find the line  "Person who gets roots email"
3. Add email address 
4. run  "newaliases" command   to rebuild the aliases database
This will ensure that all mail that the ODA boxes generate will be routed to your inbox. Initially Logwatch si setup OTB and you shoud get a logwatch email/server everyday.
