Hello everyone,
I have observed an interesting case where calendar invites send by google to
another third-party email service are being rejected on the way back (ie. when
accepted) if the receiver of the invites is in DMARC reject.
I have also observed that in some cases there are two sets of
Simon,
The out-of-band effectively sends the response through the servers of the
actual responder and not through Google' servers and that is why it passes
DMARC.

Hello all,
as far as I am aware, based on research, On-premise Exchange Servers do not
support DMARC by default and third-party plugins need to be installed.
I was wondering if anyone has already done this on their exchange server and if
they could give some suggestion on the products they

in section 9.3 of the ARC RFC it says:
"Mediators SHOULD generate DMARC reports on messages which transit their system
just like any other message which they receive. This will result in multiple
reports for each mediated message as they transit the series of handlers. DMARC

Hello all,
I have a question regarding third-party email encryption services and DMARC.
For example, when using Cisco CRES the emails contain the From domain of the

Hello all,
could someone help in troubleshooting why DKIM failed at the end recipient due
to a change in the header or body of the email? Is it possible to figure out
exactly what changed in the message that invalidated DKIM?
For example, the reason is body hash did not verify but would I be

has anyone noticed that when LinkedIn receives Out-Of-Office/Automatic-Replies

Hello, It looks like Office 365 with a gateway in front such as Barracuda or
another gateway, still does DMARC validation inbound, and quarantines any
emails that fail DMARC validation.
Should this not be the case since the MX of the receiving domain is that of the

Hi,
Does anyone know why Yahoo sends reports containing "dmarc=success (p=reject)"
and what it means? Is it the same as dmarc=pass, if so, why are they not using

what they did with
Hi Everyone,
Has any one recently seen a drop or no DMARC reports at all on a particular day
being sent from Google?
For example, on the 1st October there were no DMARC reports sent to us to
backfill the 30th September. Has anyone else got this?
