I started getting "553 Relaying disallowed as @".

Hi, after some time since my registration I started getting the error "553 Relaying disallowed as @" when try sending email via nodemailer ( https://nodemailer.com/) with the params bellow:

 
   host: 
   'smtp.zoho.com',
   
   port: 
   587, 
   
   secure: 
   false,
   
   auth: {
   
   user: 
   'no-reply@meethru.com',
   
   pass: 
   '<valid password>'
   
    },
   
   from: 
   'no-reply@meethru.com'

Is this possible only for payed accounts?

Please advise, thanks!
