[Exim] Exim 4 with no home dir?

Hello,

I checked the FAQ,
A0423: With the default configuration, you are asking Exim to check for a
.forward file in the user's home directory. If no file is found, Exim tries
to stat() the home directory. This is so that it will notice a missing NFS
home directory, and not treat it as if the .forward file did not exist. This
stat() is failing when the home directory really doesn't exist. You should
arrange for the redirect router not to run for these special users, by
adding the line

Is this all I need?
> condition = ${if eq {$home}{/bin/false}{yes}
Thanks
