I need your expertise and suggestion on this matter...
Currently, our system is using a 64K ISDN dial-up. As you all know, ISDN
dail-up is not UP all the time and it only active when there is people
surfing or activiti in the internal network. We also have a fix ip address.
We are using linux firewall and have a mail server in our local network
(behind the firewall). Our parent company have a 64K lease line. So since
we can't host our internet mail server in our organisation( we are using
ISDN dial-up), so we make use of our parent company lease line to host our
mail server. We register our domain name and whatever mail for this domain,
it will send to the mail server that we set up and located in our parent
company. So when a user want to read a mail, they need to connect to the
mail server in the parent company to retrieve mail. Sometime it is very
uncovenience and sometime the downloading mail from this mail server to the
user workstation is very very slow. So what you guy will suggest to solve
this problem?
The setup is like this:-
parent company
our company
with 64K lease line with ISDN dial-up with fix IP
line 24Hours UP
line will only UP during working hours
geografically different
places
parent.com.my
sister.com.my

1 Linux mail server
1 Linux mail server
for inernal staff and internet
currently only for internal
1 DNS server
No DNS server
(the primary domain is point to ip of parent company)
It is POSSIBLE to set such a way that whatever there is a mail to our
company (user@sister.com.my) that go to the parent company, it will foward
the mail to our company mail server? (since we have our own internel mail
server) and whatever mail to user@parent.com.my remain in the parent mail
server. If it can be done, HOW? And another thing is that how the mail
going to foward the mail to the sister company during at night (the line is
not UP) if there is a mail to one of the user in sister.com.my?
Thank your for the advice in advance.
