Unable to receive e-mail from Gmail on custom domain address
Since yesterday I can't receive e-mail from Gmail users on my custom domain address.
SPF, DKIM and DMARC configured correctly.
My fear is that we can't implement MTA-STS policy and Google use a "strict" mode rather then "testing".
Everything works with other providers.
This problem happens only on custom domain address, because I can receive e-mail on mailbox.org address.
