Mailx command
Using RHEL 5.5
New to using 'mailx'
Was trying to check if mailx is configured.

mailx command gives a list of unread mails.

Now I tried to send mail using this command to a local or on network machine using
mailx -s "Test2" "root@<servername>"

But did not receive any message.

Try to send with an email body:-
Code:
echo "This is mail body" | mailx -s "Test2" root@servername

---------- Post updated at 11:57 ---------- Previous update was at 11:51 ----------

Or without an email body:-
Code:
mailx -s "Test2" root@servername < /dev/null

As far as I can see the /etc/hosts file has the servername and IP mentioned and the local domain is mentioned in the /etc/resolv.conf

Is there usually a Relay Server in between.
Not sure how this architecture is designed.

It might be the the name resolution on the server end, I would make sure your client's hostname is in DNS.
