I know this isn't qmail specific and I apologize, but I know a LOT of people
on this list will know the answer. I have looked through several RFCs
(probably the wrong ones!) and still can't find a definite confirmation of
how I think this works. (Can anyone recommend a good overview of the email
system? I am, of course, waiting on the qmail book too!)
The setup: Dial-up access is provided on one linux box. qmail is running
on another. Both boxes have permanent connections to the internet through
the LAN. Almost all dial-up users use Windoze for connecting and reading
e-mail - if that matters.
My very fuzzy understanding of how this works: Windoze connects to the
dial-up server and uses the dial-up server's port 25 to connect to the qmail
server's port 25 to send/receive mail. Is that it, or am I missing the big
picture - again?
The point of this (other than the joy of figuring out how it works :) is
that they now want to limit some users to sending and receiving e-mail only.
If I understand correctly, I just need to find a way to limit those users to
accessing only port 25 of the dial-up server. ?
TIA
