Redmine

hello all
i having troubles receiving emails, i have only one project, i trust in all my users because I’m using redmine in a local network, i need skip to make my users to put the project: foo track:bar so i need to make import all emails from my users to an account no matter the project and the body format.
for example if an user send a email saying in the body: "hello all my account is locket" I want to receive this mail no matter the project, tracker .. etc..
Exist some way or tweak to do this????
