What to do if <domain-spec> is empty string
|
|
Grammar in "draft-mengwong-spf-01.txt" define <domain-spec> so that it
can be an empty string. We can also get an empty string after macro
expansion.
For example, following SPF record is grammatically valid:
v=spf1 +mx:/24 +a:/16 +ptr: +include: +exists: redirect= exp=
In case of a, mx, ptr mechanisms we can use <current-domain>. But what
about others?
There are two questions:
1. How to interpret empty <domain-spec> in context of various
mechanisms and modifiers?
2. What to do if we get empty string after macro expansion of
<domain-spec> in context of various mechanisms and modifiers?
