Hello,
My domain name is bigniter.com, and I’ve been using Zoho Mail as my email service provider without any issues.
The configuration was completed successfully. However, after setting this up, I’m unable to send emails from my personal Gmail account to my Zoho email address.
The bounce-back error I receive is:
It seems to be a relaying issue, possibly due to the coexistence configuration or routing settings.
For your reference, I’ve also included:
My current MX records
SPF record
Full email header
I would appreciate your help in resolving this issue.
Thank you,
