I want to set  the environment variables MAILPATH and MAIL permanently 
(i.e. make them persistent) 
I already tried the following:
MAILPATH=/home/don/Maildir
export MAILPATH
MAIL=Maildir
export MAIL
This needs to be done every time I start a new bash shell (i.e., open new terminal etc.)
How do I make these settings permanent? 
I have tried setting these variables in /etc/environment but that does not make them persistent.
