However, a logically separate MFA (Mail Filtering Agent) would perhaps
be plausible - SpamAssassin run in "spamd" mode might be an example of
this role. The MFA might be attached to the MTA, or be a plugin to the
MUA, or even reside on a separate server (potentially run by the ISP or
a third party) and be called by the MUA.
MFA = instance of "policy enforcement component" surely?
I don't think it makes a difference where exactly the policy enforcement
component resides - in the MTA itself or as another system. As per charter:
"Policy Enforcement Component: This involves subsystems within the
communication system that enforce the policy. THE OVERALL FRAMEWORK MAY
INVOLVE MULTIPLE SUBSYSTEMS WITHIN THE POLICY ENFORCEMENT COMPONENT.
No reason to complicate it by including another acronym.
