Hi there,
Please could you set up SPF, DKIM, and DMARC for my domain n747mm.heliohost.org? I turned on 'Use DKIM spam protection system to sign outgoing email messages' in Plesk about 9 hours ago, but it looks like there's more to do. Currently, mail-tester.com flags the following issues:
[SPF] n747mm.heliohost.org does not allow your server 65.19.141.77 to use n747mm@n747mm.heliohost.org
Your DKIM signature is not valid
You do not have a DMARC record
Many thanks for the great service,
Ollie
