Hi, All

My account name is airfish, after I sued to root, I found that the 
environment variable MAIL remained MAIL=/var/mail/airfish. As a result,
when I start mutt, it opens the airfish's mailbox. That's not what i
desired. But I can't find where the MAIL is set. Should I unsetenv MAIL
in my root's login file?
