Trying to deal with the Yahoo DMARC problem and am first configuring our system for Domain Keys. The documentation (Site Manager’s Operations Manual, Chapter 15) isn’t very clear.

 

What is the difference between the single domain specified in the d= option of the private key and the multi-valued LISTSERV setting DKIM_SIGN? If I specify multiple domains in DKIM_SIGN, do I need a separate domain.DKIM file for each in the LISTSERV directory?

 

Our LISTSERV runs out of a different domain than our users. Is LISTSERV signing on behalf of the list itself or the message originator?

 

When an @yahoo.com user sends a message through LISTSERV, does the message get DKIM signed?
