SENDMAIL REDHAT 9- email - firstname.lastname@example.org -problems
I have had experience with linux systems for www, dns and etc.
However, I had to rebuild a linux mail server using sendmail. I was able to get through the config and figure just about everything out but one thing.
Users should be able to send mail to email@example.com. However, if a mail message gets sent to firstname.lastname@example.org a bounce is received that says (reason:550 User not local. Authentication required for relay).
However, if i send the email to email@example.com it goes through and the user receives the message.
have tried several changes in the sendmail.mc file and I have had no luck.
Any help would be greatly appreciated.
