See "params" in Mail::SPF::Mod.

domain_spec: returns Mail::SPF::MacroString

If the given SPF result is a "fail" result, retrieves the authority domain's explanation string from the modifier's target domain and attaches it to the SPF result. If an error occurs during the retrieval of the explanation string, does nothing, as if the modifier was not present. See RFC 4408, 6.2, for details.
