Postfix Problem

[Ashwani Jain]

Hi

I am using Ubuntu 5.10 (breezy).  My mail server is configured with a
ISP.  Now I want to configure Postfix to act as a local mail server for
my organisation.  For that I have configured it, its sending and
receiving mails successfully.  Problem I am facing is that

1..   when I download mail using fetchmail, fetchmail shows that it has
downloaded mails from server but that         mail but where it
downloads mail I don't know, mail does not come into users mail box.

2..  I have two type of accounts on my ISP server.  POP accounts and
forwarding(catchall) accounts.  POP account users directly download
mails from ISP server using Internet.  But forwarding mail account users
use my local mail server to send/receive(pop and smtp) mails and on
local mail server mails gets downloaded using fetchmail.  Problem is
when forwarding mail account user send mails to POP account users whose
account is not on the local mail server using my local mail server as
SMTP server, it returns error 'this mail account does not exist' and if
I create a account on local mail server for a POP user, than this SMTP
delivers mail to local made account instead of forwarding it to ISP mail
server POP account.  This is the biggest problem I am facing and
consulted with so many people but no one has idea about its solution.

Kindly help, this is a very common configuration and must be in use in
most of the organisation.  I am new to Mail server administration and
don't know how to do it.


Thanks & regards
