White list IP on SMTP Proxy.

I am using SMTP proxy for an email server and prevent spoofing is enabled. There are some services such as voltage secure email or mailchimp that users do not receiving emails. I assume it s as result of the above or headers.
Being asked to add some IP addresses to the white list so emails coming from those IP go through. I do not seem to find settings for it. Is any setting on it or how can i address that on any way at all?

    Add a SMTP policy From: those IP addrs.

    But first, check Traffic Monitor to see what is being logged related to those e-Mails. That may point out the real issue

    here is what i find on logs:
    ProxyDrop: SMTP header
    header=From: username@acmhnyc.org
    rule_name=Prevent Spoofing

    and here is to a gmail account:
    from: username@acmhnyc.org via gmail.mctxapp.net
    reply-to: username@acmhnyc.org
    to: gmailaccount@gmail.com

    1) Is the username in the from: username@acmhnyc.org a special one ?
    If so, you can add that as an allowed SMTP header.
    If not, perhaps whoever set up the mailchimp blast can change the username to one that is special and thus one that can be allowed on your SMTP proxy.

    2) resolves to mail21.atl161.mctxapp.net
    You could try adding a SMTP packet filter From: *.mctxapp.net and see if that helps.

    Thanks for the info. Question on another matter; is it possible to copy a policy and make changes after on different name?

    No - not for a policy.
    You can clone proxy actions, such as for a HTTP or HTTPS proxy, and use that cloned proxy action on a new policy, and then make desired changes to the proxy action.
