I'm running Solaris 10/11 and need to get sendmail service to authenticate to an MS Exchange to send email. How can I achieve this. I have do it for REDHAT but I'm not sure if it's the same procedure.
On REDHAT, I have setup an authinfo file with user/password to authenticate to my MS Exchange server, some modification to sendmail.mc file and now my sendmail daemon is able to send email as long as the from address is the user that I use to connect or at least one of the aliases that we have defined for that user.
