Unable to Receive Emails after configuring MX, SPF and DKIM

Unable to Receive Emails after configuring MX, SPF and DKIM

Hi Team,

I have configured the domain gokulcapacitors.com with right MX, SPF and DKIM records on my domain. But when I try to send an email to info@gokulcapacitors.com it give me an error Invalid Address, Error Code : 550.

Can I get the solution for this problem?
