Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Mail is pulled and sent directly from mail.example.net (This is not a local server, it is off on the internet somewhere) to Outlook. A typical POP3 account.
The problem is that example.net is getting tons of spam on various accounts and I donít want to pay the spam fee for each individual mail account.
Lets say I have 20 Mail accounts on example.net
What I want to do:
Pull all of the email from example.net to my new Postfix Mail Server and have it filtered through say spam assassin and then distributed out to the appropriate Outlook clients. Spam free, well at least the majority of it.
Any HOWTO's on doing this perhaps?
Comments, Suggestions, and Questions would be greatly appreciated!!!
if you have to actually GET the mail from the net, rather than being given it, then you'll want a daemon like fetchmail to retrieve the mail. you can then get fetchmail to give the email to postfix and let that handle it, or you can deliver the email directly the local mail boxes, using procmail and spamassasin to nuke the spam while it does it. personally i'd say the latter was better, as you'd not go anywhere near an smtp server.
as for getting mail from server mail boxes to outlook clients, well i'd say just use either pop3 or imap access to that server. I'm sure there are more graceful ways to handle mail on a unix server than to have a user account for each network user, but to be honest i'm not that sure how...

I've recently implimented spamAssassin on my server and it works pretty well.
I'm doing pretty much what you want, pulling mail from external mail accounts using fetchmail, this is called from a cronjob to suit your requirements. I've also got mail coming into my server directly for another domain name and this setup has worked fine for me for a few months now.
However, like you I have noticed a massive increase in the amount of spam I get and though I'd install SpamAssassin, which I did.
Originally posted by KevinGuy Thank you for all your replies, this will help lead me in the right direction. I will let you know if I have anymore questions.
It seems that I don't even need PostFix to do this.
Just as Clarification, Postfix is used for Mail coming in correct (as acid_kewpie said)? So you would basically have a Domain and then post fix running on the Domain. Correct?
not strictly correct, I had postifix running even though my main domain was being run by an ISP, the only problem I had is lol it would not deliver mail internally IE: from webdesigner @................ to admin@...................... however all the other mails came through just fine, also sendmail worked perfectly - I shut them both down till I could set up the spamassasin and amavis - which is why I am on the forum today looking for help.
Originally posted by plisken I remember reading this somewhere actually, same end result though, I suppose...
does anyone know of a new bug/virus/ssam that when an email is opened it causes the re-download of all ( and I mean ALL) of the previously downloaded messages from the mail server? Then the ximian evolution AND outlook would not log in to the accounts.
As a precuation after posting on this list yesterday I changed all my passwords ( as any good administrator should do more often than I do at least lol :-) and started sendmail and postfix MTA .
Seems to have solved the problem but was not sure thought you all might have bumped up against this, so any ideas?
