Postfix DMARC,DKIM,SPF Setup landet im Office365 Junk Ordner

GermanQuestionE-MailInternet
Hallo,

ich bin jetzt mit meine Latein am Ende... meine mails vom Postfix landen im Junk bei Office365 Empfängern.
Ich habe folgende Konstelation:

Neuer Server mit einer frischen Postfix Installtion mit DMAR, DKIM, SPF Einträgen:

ServerHostname: mail.meinedomain.at

PTR: mail.meinedomain.at <-- löst zur Hostadresse richtig auf
MX: mail.meinedomain.at
A: mail.meinedomain.at <-- löst zur Hostadresse richtig auf

_dmarc.meinedomain.at 
"v=DMARC1; p=reject; rua=mailto:xxx@meinedomain.at.at; ruf=mailto:xxx@meinedomain.at; fo=0; adkim=s; aspf=s; pct=100; rf=afrf; sp=reject"  

mail._domainkey.meinedomain.at
"v=DKIM1; k=rsa; " 	"p=PUPKEY......."  

SPF record:
"v=spf1 ip4:Hostadresse -all"
Check gegen div. Blacklist ergibt kein Ergebniss.
Im Log sieht man auch wie outlook die Mail aufnimmt und mit einem 250er quittiert
LogAuszug:

Untrusted = Zertifikate ist nicht sauber hinterlegt.
Ist unschön, aber nicht der Grund das deine Mails im Spam landen.

Was übersehe ich hier?

Wie sieht der Email Header aus?

Hast du einen grössen auschnitt aus der Log Datei?
Am besten den kompletten von einer Mail

Danke

Hallo!

Du lieferst leider die falschen Logs. Du musst im Outlook-365 oder Hotmail-Postfach den Header anschauen. Da findest Du den Grund.

Vermutlich ist es ein Problem mit DKIM. Microsoft hält sich da nicht an alle Standards. Wenn Mails mit ISO statt UTF-Zeichensatz kommen, werden sie teilweise verändert, was die Signatur invalide macht.

https://www.postmastery.com/proper-mime-prevents-dkim-failures-in-outloo ...

Ich hatte das Problem auch und bin komplett auf UTF-8 gegangen. Seitdem ist Ruhe...
