[ILUG] Ipchains and Mail server

[Nawaz]

Hi,
I have configured my computer to be a mail server for my local lan so people
can send email to each other locally and also configured it as a gateway to
internet. When it is not connected to internet mail server works well for
local mails, but when I am connected to internet it try to masqurade these
local requests also, in a result we can send local mails, Does it needs to
create a rule in ipchains or something else..
