[Exim] [Additional] .forward and /nonexistent home directory

> How can I tell Exim not to process /nonexistent directories?
I've succeeded with forwardfile director by adding lines:
check_local_user
require_files = ${home}/.forward

but still mail is not delivered through
/usr/local/sbin/exim -v -bt webclub@???
tells that everything is ok. In the mainlog appears:
== webclub@??? T=local_delivery defer (2): No such file or directory: failed to chdir to /nonexistent

Any suggestions?
