Unable to send message
Hi,
My email ID is
notification@nimisgroup.com.
I could not able to send email to anyone from my account and it through this error "
Unable to send message;Reason:554 5.1.8 Sender Address Blocked".
Would you please unlock my email?
Also I'm using this email in an automation script to send email on day-to-day process.
What did cause this problem?
