Mailx

[solarisnj]

I have two machine's (1)Ultra 5 with a class C ip address attach to a hub and (1) Ultra 10 with a class C ip address attach to a hub. I have both hostnames and ip's in the following file /etc/hosts and I also enable the console command under /etc/default/login. How can I use the mailx to send an email from the ultra 5 to the ultra 10.

mailx on Ultra5 will use the sendmail.cf configuration to send email to the U10. By default sendmail/mailx will use DNS record MX for your domain. If you don't run DNS inbetween these two hosts you need to set a Smarthost entry in /etc/mail/sendmail.cf to the U10's hostname. Copy /etc/mail/subsidary.cf to /etc/mail/sendmail.cf first!

eg U5 = hostA, U10 = hostB
[b]hostA#[/b] grep ^DS /etc/mail/sendmail.cf
DShostB.yourdomain.com
[b]hostA#[/b]

hostB needs to run sendmail to act as a MTA
-> copy /etc/mail/main.cf to /etc/mail/sendmail.cf

sendmail tries to determine the domainname from your hosts fqhn entry, that's why your /etc/hosts entry should always look like:

10.20.30.40 hostname hostname.yourdomain.com loghost
