Having issue to send emails in AX

Hello All,

I am having issue in sending emails in AX. i am trying to send emails to customers with invoice print using SMTP server. I can able to send emails from my mail id but not able to send from one particular  mail id which is common from mail id to send emails to customers. 

Getting the below information when i am trying to send email.

 "Exception has been thrown by the target of an invocation.Mailbox unavailable. The server response was: 5.7.1 Client does not have permissions to send as this sender".

Any suggestions are welcome.

Thanks,
