Subject: Re: Mail


I have no firewall running except the security thingy in linux but that
is set to except incoming mail. Thats why i don't understand why it not
working. Also when i tried the virtualtable thingy it says something
about, actually heres the error :

# make -C /etc/mail
make: Entering directory `/etc/mail'
makemap: virtusertable.db: line 1: no RHS for LHS
damienjp gc-site hopto org       damienjp
makemap: virtusertable.db: line 3: no RHS for LHS
@gc-site.hopto                  root
make: *** [virtusertable.db] Error 65
make: Leaving directory `/etc/mail'


 I guess i'ma have to post the setup files so that maybe ya can get a
better understanding :
