Because you can lie about who you are. You're used to the Windows world where
anyone is free to do that all of the time. It's not really a good idea to allow
it though. For those companies and organizations who don't allow their users to
have root access, and who do care a lot about accountability, it's a good
constraint.

>How do I delete a user?

userdel old-user-name

>How do I stop a running daemon like fetchmail without rebooting?

killall fetchmail

>How can I transfer the messages in the inbox of one use to the inbox of
>another?

cd /var/spool/mail
cat old-user-name >>new-user-name
rm old-user-name

Note the two right angle brackets before new-user-name in the cat command. This
is important. It means append. If you only put one of them there then existing
messages for new-user-name will be deleted as the whole file will be replaced.
