Where the issue comes is with DMARC, which restricts the DKIM protocol to be aligned with the From line of the message, and thus the MLM can't make the message pass the DMARC settings of the sending domain. It is DMARC which breaks the traditional operation of a MLM, and the use of which implies that the sender should not be using such tools. -- Richard Damon
