Configuring sendmail for Solaris

In Solaris 10, here is how I will set the mail to work:

1) Get the name of SMTP server (suppose it is mail.somecompany.com)

2) Log on to the Solaris 10 server where mail setup is needed.

3) Goto /etc/mail directory

4) Edit file "submit.cf" and add/edit the line containing "DS" in Local info section:
DSmail.somecompany.com

5) Edit file "submit.cf" and add/edit the line containing "Dj" in Local info section:
Dj$w.somecomnapany.com

6) Done! Now send a test mail to verify if it is working.

---------

Once the submit.cf file is edited for adding the SMTP server's entry, try to send a mail from unix command prompt in verbose mode like shown below:

# cat some_test_file_name mailx -v -s "TEST MAIL" unixgeek@somecompany.com
unixgeek@somecompany.com... Connecting to mail.somecompany.com. via relay...

------------------

In the above output, try to look for the bold entries. If you are able to see the "Sent" and "Closing connection for ........" lines, it means that your server is able to talk to mail server of your company.

Happy mailing! :-)
