Reverse E-Mail Blockage.....

[Eddie G. O'Connor Jr.]

Hello you Ferdorans! (FedorIANS?...) I have a question,.....now....we 
all know that there's ways to block unwanted email from your system 
using Message Filters, and they work by blocking a certain domain or 
email address and prevent them from hitting your Inbox, I would like to 
know if anyone knows of a way to filter your messages in a sort of 
"reverse" order.....in other words instead of me telling the Mail Filter 
Rule: Block anything with the email address of (ABC@123) I would like it 
to be "Allow everything from (123@ABC) and block "Everything Else"...how 
would one go about doing this using Fedora 20 and Thunderbird? Any help 
would be greatly appreciated

Thank You
