AW: [exim] A weaker variant of check_spool_space

I never understood, why boolean evaluation is not supported...
I booleans were evaluated on their own, one could write:

condition = ge{$spool_space}{100M}

The construct "if x then true else false" always seems a bad construct to
me...
Maybe this could be implemented somehow, making a lot of if's redundant.

IMHO, there should be no distinction between condition results and values. 0
is false and 1 is true. exim does already behave this way in most cases...
