Thank you for contacting support. It would much appreciated, if you could let us know if your using the zoho smtp server to send out the password reset link, If yes, please help us with the Public IP address from which the connection is originated to our SMTP server, complete connection log taken from the backend of the application from which you are establishing the connection to our SMTP server.
