Hello, i use latest ISPConfig with cloudflare. So far so good, all works except sending emails. I think there is some DNS issue, but not sure where to start. When I send e-mail to gmail address: Code: The mail system <[email protected]>: host gmail-smtp-in.l.google.com[74.125.195.27] said: 550-5.7.26 This message does not have authentication information or fails to 550-5.7.26 pass authentication checks.

Hello, thank for reply. Can you send me some guide for setting those records? I can google them, but im not sure where to add them. To ISPConfig, or Cloudflare? Thank you for your time! EDIT: solved adding SPF records with help https://mxtoolbox.com/SPFRecordGenerator.aspx
Is your DNS hosted by cloudflare? Then you have to add it there. If you host your own nameservers, you'll have to do it yourself. Your PTR is setup with your hosting provider.
