OSX Firewall - Accept Incoming Network Connections Issue

Hey Guys,

I have the firewall enabled on my OSX installation, and everytime I fire up my email application for work I get the following message: ""Do you want the application 'xxx.app' to accept incoming network connections?" Found a screenshot for iTunes (not my email application) here:


Of course I clicked Accept, but every-time I launch it, I get the message. Doing some googling I found some simliar errors around the code signing of the application:

But the terminal command doesn't appear to be working in Mavericks. Does anyone have any ways to sign the application?


Thanks.

 

Anyone please?
