Security mails from Microsoft cant be delivered to Exchange 2010

Hi there,

I have strange issue with delivering e-mails from Microsoft account team to my Exchange 2010 users.

That is single Exchange 2010 server scenario with Microsoft antispam features installed.

There is one setting that is affecting behavior of that: Sender-ID filtering. If it is configured as reject messages, the authentication e-mails are rejected with error:5505.7.1Missing purported responsible address,MissingPRA,No valid PRA

I was doing some research around the Sender-ID filter and found this:https://technet.microsoft.com/en-us/library/aa997242(v=exchg.141).aspx pointing to this:

http://www.ietf.org/rfc/rfc4407.txt

(see chapter 2, points 5 and 6)

And Im thinking that the From: header is too long for the filter having 133 characters...

From: =?windows-1250?Q?T=FDm,=20kter=FD=20se=20star=E1=20o=20=FA=E8ty=20Microsoft?= <account-security-noreply@account.microsoft.com>

See https://tools.ietf.org/html/rfc2822 chapter 2.1.1

And if from header is not read properly, there is no other chance to define PRA.

Im attaching the header with some privacy related edits (*)

And also connection to my previos post:
