CSCvr76595 - ESA DMARC implementation should remove wordpress.com from the list of valid SLDs

Just to make clear what that bug does and why ...

 

Due to this bugs, ESA deletes perfectly valid and wanted emails (that are also DMARC valid) just completely.

 

And why? Just because of a clearly faulty DMARC implementation. The Rfc clearly states not to use custom TLD lists.

 

Hope wordpress knows about that ...

Ah, and to add: this bug is known to Cisco for months, and they are doing nothing against it.
