Can it be that mail that is saved in my home dir is world readable ?

[shaulk@netvision.net.il (shaul)]

I am using exmh as my MUA.
Can it be that my saved mail is world readable, or did I managed to change the 
permissions without being aware of that ?
Can an exmh user send me the correct permissions ?
