I'm trying to setup Exim on a fresh CentOS install so that it will receive mail for a collection of given addresses, and forward the mail respectively to another address. For example, receiving mail from firstname.lastname@example.org would be forwarded to email@example.com.
I figure this should be fairly straight forward... I had this working before with Sendmail, using the
virtusertable - is there something similar I can do with Exim?
I'd also like to be able to send mail, but only for mail being sent from the local machine (i.e., from applications running on the server) - I don't need/want a publicly available SMTP server.
Are there any other settings I should bear in mind to make sure the mail server is secure? (i.e., prevent relaying) I'm assuming that it will be secure out of the box.
