Hello Zoho Support Team,

I am experiencing a critical issue with sending emails via Zoho SMTP for my domain humanhup.com. Both of my applications, HumanHup and CheapUI, are unable to send emails using Zoho SMTP, even though the same setup was working fine before.

Details:

• SMTP Server: smtppro.zoho.eu

• Ports tried: 465 (SSL) and 587 (TLS)

• Username: 

• Password: 

• Error: Unable to connect/send emails; connection times out or fails.

I have tested sending emails via Mailtrap with the same applications, and Mailtrap works perfectly, so I am confident the problem is related specifically to Zoho SMTP.

I have also verified my server’s connectivity to Zoho SMTP servers but still cannot send emails.

This issue is severely affecting my business operations, and I urgently need your help to restore email sending functionality.

Please assist me with troubleshooting or let me know if there are any blocks, restrictions, or changes in policy that might be affecting my account or domain.

Thank you very much for your prompt support.

Best regards,
