Different Attachment Filtering Ruleset for Whitelisted Emails
Currently, Attachment filtering can be configured to test whitelisted emails, but only a single set of rules can be configured for both whitelisted and non-whitelisted emails. A different ruleset for whitelisted emails would provide a finer control over attachments.

Weighting of DNS and URL Blacklist
Support weighting of different DNS and URL Blacklist. Reliable lists would reject the email on the first hit, other (more aggressive, and therefore unreliable) blacklists would only raise the "suspicion level", and ORF would require additional hit(s) from other blacklists to reject the email. If no such additional hit is logged, the email is allowed through.

Configurable Action for SPF Errors
Configurable action for unresolvable or syntactically incorrect SPF records. This feature would allow tagging or rejecting emails if the SPF record of the sender domain is syntactically incorrect, or cannot be resolved due to non-existent DNS records.
Vamsoft disclaimer: Please consider that having a syntactically incorrect or unresolvable SPF record in no way indicates the sender is a spammer (such problems could be caused by configuration errors, or temporary DNS issues, which are quite common), so blacklisting emails based on this criteria is guaranteed to cause false positives (losing legitimate emails).
