help with procmail and sendmail 8.8.8

when i add the $home/.mail to the authencation.c file and send mail i
get the following error in the mqueue dir

procmail: Couldn't create
"/export/home/users/d/dstinson/export/home/users/d/dstinson/.mail"

and here is the line from the modified .c file
#ifndef MAILSPOOLDIR
#define MAILSPOOLDIR "/var/spool/mail/"      /* watch the trailing / */
#endif
#ifndef MAILSPOOLHASH
/*#define MAILSPOOLHASH 0      /* 2 would deliver to
/var/spool/mail/b/a/bar */
#endif
#define MAILSPOOLHOME "$HOME/.mail"        /* watch the leading / */
        /* delivers to $HOME/.mail */
#define STRLEN(x) (sizeof(x)-1)

any ideas on why it is doubling the home dir????????
