Add 'Remove cc' trigger/automation action

My solution was just a suggestion to remove all CC's. Excepting changes to Zendesks targets, it works. I suspect a smarter brain than me could do better.
The other suggestion was to build an app for this, noone has contacted me about this.
The havoc I referred to was relating to DLs which are handled by mail servers -how the heck can Zendesk change a mail server behavior?

Your solution doesn't work. Even as you said, that doesn't prevent it from causing havoc. The functionality as its been requested from multiple users and companies is what's needed to properly resolve this.

+1 to this!  Our use case is when a certain macro is applied, we want to automatically remove everyone in the CC list.  I am also looking at triggers or automations that would do the same either on macro application, or if the case is received from a certain user.  But none of those apply either.

OMG 8 years and still not resolved.

This one guy that logs calls , CC's Zendesk , and me as well , now i keep getting the updates on his calls logged. It doesn't even have anything to do with me.

8 Years zendesk , please.

@isaiah, I don't know why this is difficult sorry

Hey Sara, what I said about not being a Zendesk issue was in relation to the first email someone adds to a DL. Possibly I do not understand how this is happening for you, but if a person adds a CC to an email in their email client or webmail, this goes to your mail server for distribution right? This is not able to be filtered by Zendesk.
Can you consider adding the DL to support emails, preventing CCs?
Sorry I cannot speak to all the issues, it is one I am interested in, but I am a Zendesk user like yourself.
There may be way to handle some of these issues in Zendesk.
Handling issues outside of Zendesk (ie. In a sender's mail client) is customer education, and something that would be encountered no matter how this is handled. That said, I'm sure it's possible to improve control of this once it hits Zendesk.

The ask is to create a "Remove CC" trigger action.  Why is that such a difficult request?  If you can have an "Add CC" trigger, why not be able to remove specific CC's via trigger?

That solution doesn't work. One of the email lists is our mail Zendesk Guide email that needs to NOT be blacklisted. This IS a Zendesk Issue because Zendesk hasn't given us a way to handle CC's that we literally cannot control a customer adding without remove ALL of their CC's, including their own, valid CC's.

The fact that there is no solution to this issue after obviously years of pain points for multiple customers (based on the comments) ignores an obvious need in the product that is literally a product issue because we cannot control what external customers add to the CC field.

We'd like to look at an app for this functionality.
Anyone can email me if interested, preferably with their wishlist on features/function and a little detail on their Zendesk environment. Email is in my profile. Please do not ask, or give details in the forum.

@sara, we don't have DLs so I have not tested this.. would you try adding the DL to the support email list (or even the blacklist?). Adding to the support email list prevents it being added as a CC. Of course this will not prevent the first email going to everyone and creating possible havoc! But that part is not a Zendesk issue right? There may be rules you can add to your DL that will filter out support tickets added later, but be cautious about if this is ever genuinely desirable.
