Hey guys:

Now, all of our mail lists' dmarc mitigation policy has been upgraded into "only when sender's  DMARC  equal to p = quarantine or p = reject", that means now we would not change email's content (Sen from Someone via Tc) at most of the cases. and the behaviour of Reply to would work as expected.

Sorry for inconvenience.
