can't receive emails

can't receive emails

I bought my domain in zoho set up the email account and tried to email to info@nuinvestllc.com from my mindspring account and get failed message:
Info@nuinvestllc.com
SMTP error from remote mail server after RCPT to: info@nuinvestllc.com:
host mx.zoho.mail.com (72.5.230.114) : 553 Relaying disallowed

do I have to wait for some time before Zoho has create all the necesarry setting to receive emails from other ISP.  I was able to send out an email to my mindspring account.
