Add an option to never log emails FROM a specifi domain


Some emails need to be kept confidential, even from people in your own company. Users need to be able to choose this settings in the NEVER LOG list on the Sales Extension. 


This will prevent confidential content to be shared without notice, private data to be shared without knowledge of it. A good example of this is a merge negotiation, taxes or private HR matters done by email and logged in the CRM. 


The NEVER LOG feature only considers emails SENT to a specific domain, and not emails FROM that said domain.
