If spfquery.pl is called from ${run..}, there is no need to dive into
perl driver module. Passing some variable(s) to SPF or DMARC modules
should be sufficient. Add name for new condition to set internal state
in spf.c (say, "spf_force_status"), and syntax could be like that:
warn
set acl_m_spf_status = ${run{/path/to/spfquery.pl ...}}
spf_force_status = $acl_m_spf_status
BTW, DMARC can also be implemented externally.
