I don't immediately see that anyone more knowledgable replied,
so I'll toss out some possibilities/confirmations:
Yes, you need something like a Linux box. It will run
SA, and will retrieve mail using pop3 from your current provider.
Pop3proxy is one possibility. Another possibility is Fetchmail feeding
into a local mail system.
I don't recall if you said how many users you have, but my
impression is it is no more than a few thousand, perhaps only a few
hundred. At this size it would be feasible to set up an account on the
linux box for each user, and deliver mail into these accounts.
Basically you can use Fetchmail to grab the mail from your
current pop3 server and stick it into the standard unix mail files for each user
on the system. Then you can use a pop3 server on the linux box so your
user can grab their mail out of these accounts. SA would be in the middle
of that process, probably something like
Fetchmail->procmail->SA->mailbox->pop3server.
You users don't need actual access to these accounts, or even
know that they exist, and I think you can set them up as no login. All the
users will have to do is change the hostname in their pop3 mail configuratios
for where they grab mail. Unless you want to run outbound through SA also,
they won't have to change the current smtp info pointing to your external
provider.
This is essentially how we have things set up
here.

Subject: Re: SpamAssassin w/POP3 &
SMTP outsourced e-mail server...
Let me try and summarize what I have recieved from all these
e-mails as well as put together myself. Then you guys could give me some
feedback if I'm on the right trail. What I need to do is install SpamAssassin
w/pop3proxy on a linux box. Then setup the pop3proxy to point to my external
pop3 server. On the client side I will need to setup each client's login to
include their login name and the SpamAssassin/pop3proxy server (I'm not sure
if I can only do this if I use the SAproxy utility for windows). Thats how I
understand this should work. Now configuring this is another situation. How
does it look to you guys? I have just noticed that there are a lot of
utilities and stuff to use and am trying to piece it all
together.
thanks

So
you must have SAproxy on each client to do this? I know that is another
product that I have heard of. If so do you have a download link where I can
get SAproxy? If that is just the name you are calling the SpamAssassin proxy
it looks like all I would need to do is specify the destination server in
the login box and I'm set. All I have to do on the server end is setup the
POP3proxy. Is this correct?

We installed it on a linux box with
SA, and run it as a deamon. It
supports concurrent connections,
altought we haven't tested it
thoroughly (hundreds of simultaneous
connections...). So, rather than
installing it locally on each
machine, use a shared POP proxy.
The client sends SAproxy the
user/password, that then SAproxy submits to
the remote server. It is a
proxy for POP3 protocol (no support for
POP3*S*), just that before
sending the message to the client it is
scanned by SA.
It is
also very flexible, since the destinaton server has to be
specified as
part of the login string ([EMAIL PROTECTED]
to retrieve
mail with login [EMAIL PROTECTED] from pop.domain.com
server):
your colleagues can use the same proxy box for retrieving mail
from
other POP3 accounts as
well.
