I've been using courier for awhile now and I think it's a great piece of software. I am, however, not quite clear about how to configure it as a backup MX server.
>From the FAQ I can read that:
"Furthermore, the hostname in the MX record must be one of the hostnames in the
locals configuration file."Is it absolutely crucial that this hostname exists in 'locals' or does it follow normal semantics and defaults to 'me' when 'locals' doesn't exist?
Also, I'd prefer to not have any mail delivered to the machine acting as a backup MX. But the constraint above makes it consider any mail to <[EMAIL PROTECTED]> to be a local mailbox. If it is possible I'd like it to forward this mail to <[EMAIL PROTECTED]> instead. Setting up an alias for every user is not an option. I need some kind of catch-all.
If this is not possible, then can I configure it to bounce all mail heading for <[EMAIL PROTECTED]>? There are user accounts on the machine but I don't want them to receive mail.
I don't know if you're supposed to retain some accounts going to specific mail servers (<[EMAIL PROTECTED]> comes to mind). If so, I'd appreciate any pointers on what's customary to have set up. Maintaining aliases for some system critical stuff is acceptable, having to put up a new reject rule for each new user on the machine is not.
