Re: Sending email in a closed network
You can use /etc/hosts networking to resolve the name of the mail server and use DS smart relay in sendmail.cf
You will still need a mail server that accepts mail for relay or storage.

Re: Sending email in a closed network
On RedHat Enterprise Linux 5, you should edit /etc/mail/sendmail.mc to un-comment and edit the SMART_HOST option line to point to your mail server, then run "make -C /etc/mail" to regenerate your /etc/mail/sendmail.cf, then restart sendmail.
Please see:
http://kbase.redhat.com/faq/docs/DOC-10659
To have /etc/mail/sendmail.mc in RHEL 5, you must install the "sendmail-cf" RPM package from the standard RHEL package collection.
Also make sure that your /etc/hosts lists a fully-qualified hostname for your server: sendmail will keep complaining if it cannot find out the domain part of the host name.
If you don't use DNS, make sure "dns" is not mentioned in /etc/nsswitch.conf: otherwise sendmail may waste time in attempting to use DNS and failing.
