I need a solution
Hello, we cannot send emails to any of your customers located on cluster3.eu.messagelabs.com. Messages queue at our side with the error: lost connection with cluster3.eu.messagelabs.com[46.226.53.54] while performing the EHLO handshake.
I have checked the RBL lists and we appear to be clear for spam activity. Would you please investigate why this would be the case?
Thank you.
