[Exim] save command in filter fails ???

Hi exim-users,

I have this systemwide forwardfile:

# Exim filter

if $recipients: contains "httpd"
       then  save /var/mail/httpd
elif $recipients: contains "mydomain.com"
        then deliver ray@???
             deliver john@???
             deliver john@???
endif

The deliver part worked ok, but after i added the save command i get
this error in the paniclog:

1999-10-22 21:30:07 11ejue-00027c-00 == /var/mail/httpd <message filter> transpo
rting defer (-1): No transport set by director

What the heck is wrong ?? Everything worked ok before i added the
first test. And in the docs i couldn't find any extra things that
needed to be set for using the save command...

If possible please copy a reply to my private emailaddress.

Thanx!
