Hi @Sasa Swedi , The error message you are seeing indicates that the domain "masvenarch.com" has a Sender Policy Framework (SPF) record that is failing SPF checks. SPF is a method of fighting spam by verifying the sender's IP against the alleged owner of the "From" domain. It looks like the IP [2a01:111:f400:fe1f::716] is not authorized to send emails on behalf of "masvenarch.com". To resolve this issue, you need ensure that the server's IP address is included in the SPF record for your domain. The SPF record is usually a TXT record in the DNS settings for your domain. You may need to contact your domain registrar or DNS hosting provider to change your SPF record. If you do not manage your own DNS, you may need to contact your email or web hosting provider for assistance. You can read more about SPF records and how to create them from this page.
