iterative SPF lookup
This module provides an iterative resolving of SPF records.  Contrary
to Mail::SPF, which does blocking DNS lookups, this module just
returns the DNS queries and later expects the responses.

Lookup of the DNS records will be done outside of the module and
can be done in a event driven way.
