opendmarc relies on the presence of Authentication-Results fields to 
figure out whether DKIM or SPF passed.  In normal operation, opendkim 
would run and add that field after DKIM checking is completed, and then 
opendmarc would get the message (including the added field) and figure out 
the DMARC result based on that.

In command line mode, you'd follow these steps:

1) Run "opendkim -t" to verify the message.  This will yield an 
Authentication-Results field indicating the DKIM result.

2) Copy that Authentication-Results field into the header of the sample 
message.

3) Run "opendmarc -t" to run DMARC checks on the modified version of the 
original message.

Does that make sense?
