Set the obligatory report methods?

[Kārlis Repsons <ka...@gmail.com>]

Hi again,
[hopefully that is not- or documented somewhere deep]
presumably, when all spam reporting methods have failed, I get this warning: 
"warn: spamassassin: warning, unable to report message". 
My question: is there some way to set the obligatory report methods, missing 
any of which would result in an error return value (for example, when 
pyzor/razor failed because I had a heavily loaded router, but other methods 
didn't)?
