here is my use story:
I use DavMail to connect to my organisation's O365 service. The 
organisation is now approaching implementing its government's policy 
that is expected to force public authorities to use DMARC (which 
occasioned me to write).

The reasoning of my organisation, which is a public authority, is that 
occasionally, its name is misused as an alleged sender to increase 
credibility and to render phishing attacks more likely successful.

To counter such misuse, so the reasoning by the organisation is, DMARC 
is to be used, which they expect will effectively decrease the number of 
fake emails.

Whether that promise will be realised or not, DavMail as a Third Party 
system with which I access the O365 server, will not be able (as far as 
I understand it) to signal effectively to the recipient that it my 
message is not spam.

Ok what is that country? Denmark ;) Here are the Danish language claims 
underlying my organisation's reasoning:

So, with DMARC capacity, in my understanding, DavMail would be able to 
ensure that receiving servers that conduct DMARC checks would validate 
my messages as indeed belonging to my organisation's O365 system.

Ok, I hope this effort helps to provide the relevant context, if not I 
am happy to try to answer more specific questions. And I like to 
apologise in case my understanding is so minimal that all this conext 
"obviously" does not make sense.

Thank you for your reading!
