I am running Red Hat ES 4.0 and want to configure sendmail (mail or mailx) to send all email for unknown users to my other email server without appending the domain name.
Ex: user name is joeuser on the linux box my application can send the email to joeuser, but without an alias of firstname.lastname@example.org
it will remain on the local unix box. I would like to be able to have my application send an email to joeuser and not have to set up an alias for all users. Is there a way to configure all emails without the "@mydomain.com" to automatically be forwarded to my mail server without the "@mydomain.com".
Thanks for any help.
