I tried to configure SMTP for my WordPress site to use the email noreply@example.com.

I am getting an "Incorrect authentication data" error.

I tried two WordPress plugins but got the same result.

Here are the settings I tried:

Host Name: I tried both smtp.zoho.com and smtppro.zoho.com. Port: 587, username: noreply@example.com, and password (I double-checked this, and it is correct).

What could be the reason for this? How can I fix it?
