[exim] /etc/aliases

hi all

I have

all: :include:/etc/twousers in my /etc/aliases file. I want that if i
type all@??? it should go to the users in /etc/twousers file.
also enabled pipe_transport=address_pipe in exim4 config and have given user
= and group = options. It was working for quite sometime.

Of late exim4 throws this error and does not deliver

error in redirect data: missing or malformed local part (expected
word or "<") in "include:/etc/twousers

once and another time this error came

2005-05-18 15:08:16 internal problem in system_aliases router (recipient is
all@???)data from subprocess: status=0100 readerror='N
o such file or directory'

i did newaliases to vain.

I run exim4 on debian sarge. Anybody can give me some clue. No changes had
been done to the system config as such

Thanks in advance

Thanks & Regards
