<p>My understanding of the "fo" option is that it is only used for reporting. i.e. It doesn't control whether the received email is accepted or not, which is always based on <em>either</em> SPF or DKIM checks passing.</p>
<p>From RFC 7489:</p>
<pre class="v1v1newpage"> fo: Failure reporting options (plain-text; OPTIONAL; default is "0")
Provides requested options for generation of failure reports.
Report generators MAY choose to adhere to the requested options.
This tag's content MUST be ignored if a "ruf" tag (below) is not
also specified...</pre>
