[Solved] E-mail dns settings Setup - SPF, DKIM, and DMARC

[developer1]

Hi there,

Please could you set up SPF, DKIM, and DMARC for my domain 'ngo.helioho.st' and it's associated alias. In Plesk’s “Track Email Delivery” I see messages leaving the server, but Gmail is bouncing them with error 5.7.26. In Mail Settings for ngo.helioho.st, I tried to turn on 'Use DKIM spam protection system to sign outgoing email messages' in Plesk but it shows “This option is not supported”, so I can’t enable DKIM myself.

Could you please:

• Enable DKIM (and SPF and DMARC ) for full mail options for ngo.helioho.st, and

• Let me know what SPF / DKIM records or settings you recommend for authenticated sending,

• and/or confirm that I can/should instead use an external SMTP service for sending and if so, what are the recommended settings so that i can implement for
  my other domains when the time comes without having to bother you?

Many thanks!

DKIM, SPF, and DMARC have been set up for the domain ngo.helioho.st. We recommend sending a real email (not just the word "test" or a blank email) to https://www.mail-tester.com/ to make sure that everything is set up correctly. If you get less than a 10/10 score please post a link to the full report so we can help you fix any other issues that there may be.
 

Please keep in mind that there is a sending limit of 50 emails per day. If you need more, you'll need to answer a few questions regarding who and what you're sending and we can increase that limit.
