I usually overcome this problem by using $HOME in my scripts. I
think this is a better way because you can put it in the middle of
double-quote quoted strings (but not single quotes.)
export MAILPATH="$HOME/mailspool/rusty:$HOME/Mail/z?Zsh mail."
IMHO its a good habit to get into.
better understand parameter expansion??
echo $HOME "$HOME" '$HOME' ~ "~" '~'
/home/wheel/dunc /home/wheel/dunc $HOME /home/wheel/dunc ~ ~
