Re: Temporarily blocked...not

Because their CGPro server redistributes your email to all subscribers of the list [email protected] 

As DMARC does not only check the Return-Path (Envelope From) but als the "From:" address for forged sender addresses, it will fail this check.
This is the case with ANY mailing list our there and also any automatic email forwarding that recipients may have configured.

DMARC and to a lesser degree also SPF (SRS anyone?) is "broken" in this regards and that's why I woun't recommend to use these technologies.
