Dmarc and Dkim function

[barbours]

I operate a inbound only filtering EFA 4. I would like to know if that will allow the filter evaluate incoming emails and deny those senders that don't pass dkim, spf, and dmarc. I have enabled it on the EFA menu, but looking for proof that the EFA filter is evaluating dkim, spf, and dmarc on incoming email.

If you are filtering on the spamassassin level, you will be able to see it in the spam score for the rules that test for dkim, spf and dmarc.

If you want to test a particular message, then run the message through spamassassin using debug mode:

Code: Select all

spamassassin -D -t < [mail messagefile somewhere under /var/spool/MailScanner/quarantine/] 2>&1 |less

give it a moment and then you can search for the tests to see if they've run or not.

(personally, I prefer '|vim -' rather than '|less' as I find it easier to work with when searching)
