[gentoo-server] courier-imapd with a proxy/backup server ?

[Claudinei Matos]

Yeah, I saw that the problem is ocurring 'cause all the users share
the same ip which one is the ip of the internet gateway.
Anyway, with the new limit of connections everybody can retrieve mail
but some users are annoying me about the speed to access the server.
What I want is that the messages that arrive at my MAIN (the one at
the hoster)  server could be redirected to my proxy/backup server (the
one at my local network) or if it could be, that the proxy/backup
connect to the main server to catch all the accounts messages.
I know I culd just use my local server as my MAIN MX but the problem
is that this server is connected to internet by a adsl not confiable
and with dynamic ip link. So I was thinking if I could setup this
local server as my primary MX with his dyndns hostname and put the
"old main" server as the backup MX, just in the case adsl link get
down.
I've also got a quick look at
http://www.courier-mta.org/imap/?README.proxy.html and I saw that I
can setup a proxy server to my users, but I don't know if that could
be a solution too.

Any advices would be appreciated.

Tks,
