I have an exim installation on host [A}, i want to pass the service [backup MX, to collect email in case of maintenance stop for the main server] to another server [B]. It is enough after installing exim4 [both have same version 4.96 from bookworm] on server B to copy all configuration files to the new server?
My preferred way is to have a config which handles either being the primary MX for the overall system, or being a secondary which forwards to the primary. The secondary can then be running well in advance of any primary outage, planned or not, and will merely queue if needed (and deliver eventually on queue-runs once the primary reappears). Your use of the name "exim4" implies a Debian (or related) system [nobody else calls Exim that. Exim version 3 went obsolete twenty yeas ago]. You should look at Debian docs regarding secondary MX installations if you are running their configuration. If your config on B thinks it should be delivering to files, you'd end up having to deal with all those files, which I call suboptimal. -- Cheers, Jeremy -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
