While I'd have to agree with you, there are some caveats so it depends what
risk one is willing to take.  "Should" and "will" are 2 different concepts,
not all mail servers are RFC compliant and though 5 days is the default in
some mail servers it's a configurable option in all I've worked with IIRC.
So if your primary is down for an extended period or any of the other
assumptions aren't true then your primary machine's users may not receive
mail sent to them when the primary is inaccessible.
