Auto Reply deny list for automated emails sent to Zoho Desk

Auto Reply deny list for automated emails sent to Zoho Desk

Hi, 

We want to implement an auto-reply deny list for domains that send automated emails, which we direct to the helpdesk. 

There are a couple of posts about this, but in the workflow example below, Actions->Send Alert->Notify Contact isn't an option.

What are our options for this functionality please?

If we create a new alert using the rest of the workflow above, will that stop the auto-replies for the domains we list in the workflow
Criteria->Email does not contain " "(include the addresses that need to be skipped)?

Cheers

Jim
