Email NOT sent to Gmail with Netlify DNS

  • Hi everyone! I have webhosting and email from Netcup and have created a website which I've hosted on Netlify

    Email has been working fine for some months but now I receive a mail failure when emailing to Gmail as such:

    I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

    said: 550-5.7.26 This mail is unauthenticated, which poses a security risk to the 550-5.7.26 sender and Gmail users, and has been blocked. The sender must 550-5.7.26 authenticate with at least one of SPF or DKIM. For this message, 550-5.7.26 DKIM checks did not pass and SPF check for [] did not 550-5.7.26 pass with ip:

    I've pointed the DNS in Netcup to Netlify's and have the following DNS added in Netlify: 10 in MX 10 50 in MX 50 3600 in Netlify 3600 in Neltify

    what else should I add to make SPF and DKIM work?

    Thank you!

    For SPF: TXT "v=spf1 mx a ~all"
