Email is getting rejected

Hi,

When we send emails from our server to any partners that uses a Symantec solution we get this respons:

Remote host said: 601 Attempted to send the message to the following ip's:

The problem started when we started using our new email server.

Blacklist check on Mxtoolbox: https://mxtoolbox.com/SuperTool.aspx?action=blackl...

Our reputation on http://www.symantec.com/security_response/landing/... is Neutral.

Can you plese help us, so we can begin sending email til Symantec customers as well?

Kind regards
