Yes, I can understand that relay.sap.com should have entry in /etc/mail/relay-domains( Am I correct?But on RHEL Machine I dont see any file with that name. Do I need to create that manually ).
Which will be sendmail server here(I am confused
As far I know, We make those relay-domain entry in Sendmail Server Right?
But about the sender.sap.com.
what configuration on sender.sap.com will direct mail to relay machine?
I mean to ask - how will sender.sap.com know where is relay machine or whom to relay?
