Hello, I am trying to figure out why my Postfix disconnect after EHLO command. A customer is trying to email me something but Postfix disconnect: ( on the customer side this is the bounced message "Remote Server returned '< spring1.mydomain.com #5.0.0 smtp; 554 Security violation. Email Session ID:" )
your help is appreciated!
