Hi Guys, I have implemented DMARC for long with p=none rule with a minimal and sporadical Threat/Unknown sources, but recently I had to increase to p=quarantene and then to p=reject because I'm having a lot of Threat/Unknown sources (25% rate). It seems that lately my domain is under serious attack. I'm pretty sure I have zero impact of my legit email flow because each configuration is good, therefore every Threat/Unknown source is not legit (most of all from China).
Someone more experienced of me can tell me if this rate is usual? Is there something more that I can do to minimize it? Thank you very much. *Denis Salicetti* <http://linkedin.salicetti.it/> Avviso di riservatezza <http://goo.gl/zS2xL> | Inviami messaggi protetti <http://goo.gl/LbhIoi>
