Was thinking it would be wise to backup my server, in case anything "bad" ever happened, so that I could quickly get up to speed.
Thanks for asking (I could not find a lot of threads about it when I looked into it.)
I am obsessive so I have a forward-all rule in POSTFIX that pipes to a command line from which I cast to another server where I save (and replicate to another server and so on.)
This is what I do ,what I'd recommend is that'd be a feature delivered with POSTFIX (since it's the `first' program to receive the email and tell the sender that it's ok, it's been received. Perhaps that's why I did not find much: I was focusing my search around POSTFIX.)
Now I understand one is supposed to have a back up email server but that's for if the internet facing one is down/disconnected ? I think there is something in the standard to say to reasonably retry.
I'm here originially to set up my system on my iPhone with server-side rules. (Thus only realizing there seems to be a built-in backup mechanism in Dovecot?)
