Sending outgoing mail with the mail client (Spark Mail/Outlook) is always marked as spam

Hi

Sending outgoing mail with the mail client (Spark Mail/Outlook) is always marked as spam. But if I send with webmail is Ok.

Can you shed some light?

Cheers!

Send yourself an email and watch the mail headers and the exim logs

Hello,

In the headers of the email marked as spam:
ARC-Authentication-Results:
dkim=pass…
spf=pass…
dmarc=pass…

Received-SPF: pass
Authentication-Results: mx.google.com;
dkim=pass
spf=pass
dmarc=pass

I don’t see anything strange in the exim log.
