Fix Zoho SMTP Sending Issue

Job ID: 40440240

Budget: $30 – $250 USD

My Zoho mailbox receives every message that is sent to it, but anything I try to send just sits in the outbox and never reaches the recipient. Since the service provider in question is Zoho, I suspect the trouble lies in the SMTP configuration—possibly the port, authentication method, or a missing DNS record.

Here’s what I need you to do:

• Pin-point the exact cause of the sending failure inside Zoho Mail.
• Correct the SMTP settings and, if required, update SPF, DKIM or DMARC records at the DNS host so external servers accept my mail.
• Prove the fix works by sending test emails that successfully reach major providers such as Gmail and Outlook.
• Leave me a short note outlining what you changed so I can maintain the setup in future.

Once outgoing mail flows normally and the test messages land without errors or bounces, the task is complete.
