How change email security

Hello Suddam,

I don’t think there is a switch / button for that.

So you’d need to start customize the code of the CRM to your needs.
There are two main approaches:

  1. You are a developer and you want to try to learn about the code of SuiteCRM to accomplish things like this. Starting point here is the documentation to understand the structure and concepts somewhat: Developer Guide :: SuiteCRM Documentation and you can quickly search directly in the code via GitHub (Suite 8 in this case)
  2. You’d hire someone to customize your CRM (since there is still more to it than the links from before - upgrade safe customizations, deployments, versioning, multiple environments etc.)
