I'm Charles, 30 years old, system & network administrator in a french hospital.
Thank you for this very nice project !
Very intersting & performing, it's the product that I expected !
I've tested two paid solutions, (Sophos and Netasq), but they are less effective.
The interface is complete and easy to use, and with the "Mass Import Script" it's very nice to add a spam blacklist !
Congratulations and long life to EFA !

Sincerelly.
Charles.
