    First, the mx's IP was 184.53.48.217 (your IP doesn't matter, since you're not the email server). It is not discretely listed in the DMARC spec, but may be a part of one of the two includes listed.

     

    Second, a simple host lookup of 184.53.48.217 gives me host1845321748.direcway.com, which might be an alias to smtp02.hughes.cmh.synacor.com, but who knows.

     

    Finally, it looks like almagourmet.com rejected your email on an SPF Softfail when hughes.net has a DMARC record in their DNS, but:
        a. no policy is listed (usually set to reject or quarantine if there is an SPF failure); and
        b. The DMARC spec ends with a "~all", which means to softfail any IP that's not listed.

    Bottom line: Seems like almagormet's settings are a little severe in that they're not following the policy recommendation, nor are they dealing with a softfail correctly.
