I have a server running Postfix 2.6.5, and all of the local users have email accounts through the company ISP. These accounts have the same usernames as their usernames on the server.
I would like any locally sent email (i.e., sent to email@example.com or just joe) to be sent directly to the ISP accounts (i.e., firstname.lastname@example.org). I don't want the users to even have mailboxes on the server.
smtp_generic_maps looks close, but I think it requires a separate line for every user in the system. Do I need to put regexps in
generic? Or is there an easier way to do this?
