Client does not have permissions to send as this sender " (code: 550) (send)”

Hi,



Am am getting this error "Client does not have permissions to send as this sender " (code: 550) (send)” when using our Microsoft Exchange SMTP server.



Does anyone else have this problem. I can connect successfully and can send a test mail but not a mail to a contact.



Thanks,

Chris

Test your SPF settings, is the server you have Mautic installed on, part of the SPF whitelist in the Microsoft Exchange server?

This is a problem relate to Microsoft Exchange no Mautic contact your Microsoft Exchange Administrator
