No, the 'fail' is a forced failure. This is not the same as returning
the string literal 'fail'.

    # forced failure
    exim -be '${if eq{a}{b}{is equal}fail}'
vs
    # a string, just interpreted as FALSE in some condition
    exim -be '${if eq{a}{b}{is equal}{false}}'
vs
    # just a string 'fail'
    exim -be '${if eq{a}{b}{is equal}{fail}}'


In some places there is a difference between returning the literal
'false' and a force failure;
