My VPS Linux server hired from Godaddy has 10+ domains hosted in it. None of them are able to send emails to Zoho hosted mails. Mails to other domains (Gmail, Live, Yahoo etc.) are working well and hit in inbox (Not spam). The log from cPanel shows that the mails are getting delivered to dedrelay.secureserver.net, not to the target mail server. Zoho logs indicates that, mails are not handed over to Zoho server.
Is the issue because of problem with dedrelay.secureserver.net? Any one else have faced similar issues?
I have DKIM, SPF and DMARC in place.
Any help is appreciated.
