Hi Support,
I used Zoho email service to receive and send emails under my domain (following your MX and SPF instruction, it was easy). My domain hosting was with another vendor. Everything was great then. But there is a problem now.
From last year, my domain was deactivated. Following the deactivation, I received two notices from Zoho that the DNS MX and SPF records were not pointing to Zoho any more, which was expected.
Now I re-activated my domain and also reconfigured the MX and SPF on the DNS record. I can receive emails sent to my domain at Zoho Mail now, but I can't send any emails. I get an error message "Unable to send message;Reason:553 Relaying disallowed." At Zoho Mail Admin, I can see the SPF Status For Domains says verification completed successfully. But what is it I am missing?
Thanks.
