sendmail: directing mails to different relay hosts.
Being new to sendmail and having looked in the documentation, I still can't answer the following question that arose in our organization;
We would like to send emails directed to certain users to a different relay host as all other emails. For example emails directed to firstname.lastname@example.org should go directly to monitorhost.domain.com while all other emails should go to mailserver.domain.com.
I guess it is possible, but I couldn't figure it out that quickly with the documentation on hand. Any help s welcome.
