Q. I have installed and configured qmail successfully. Everything is working fine except that mail for loacal user can not be read using mail command. How do I fix this problem?

A. If you are delivering mail into ~/Mailbox for each user instead of /var/mail directory, you need to setup few things so that mail can read using mail and other command line tools.

Type following command at shell prompt:

$ MAIL=$HOME/Mailbox
$ export MAIL

Now type mail or mutt command to read mail from local mail box:

$ mail

OR

$ mutt

You need to make sure that the MAIL environment variable for all of your users is set to $HOME/Mailbox instead of its default value in /var/mail.

Open your /etc/profile (bash/sh shell) and add following lines:

# vi /etc/profile

Append following lines:

MAIL=$HOME/Mailbox
export MAIL

Save the changes.
If you are using CSH shell open and add following lines:

# vi /etc/csh.cshrc

Append following lines:

setenv MAIL $HOME/Mailbox

Save the changes.
