Hi all,
I wondered if anyone else has observed what appears to be DMARC records
intermittently disappearing for domains that are hosted at Proofpoint?
I.e. many domains have a DMARC record such as:
IN CNAME _dmarc.xxx.com.dmarc.has.pphosted.com
The associated TXT record for _dmarc.xxx.com.dmarc.has.pphosted.com
appears to be intermittently missing. When referred to, it does exist,
but in some cases the TXT record is empty: it does not contain the DMARC
data. This empty record is correctly dnssec signed, which makes me
think that it is a problem at the source.
If there is anyone from Proofpoint on this list then I would be happy to
provide the detailed logs.
Many thanks,
Andy
