Hello again,
I eventually gave up with Mandrake and installed SuSE 8.1 Professional instead on both my machines. Works much better and was totally easy to set up.
So now I have a different question if anyone can answer it... (I don't think its a hard one... )
I have two machines in my mini home network, one dual booting MSW98SE and SuSE8.1Prof and the other just booting SuSE8.1Prof (because its only got a diddy 4Gig hard drive so it didn't seem worth putting both operating systems on it.)
One of the machines connects to the internet via 56k modem (I intend to upgrade to ADSL in a few months time but am working with this set up for now). We use KMail as our mail client, and I would like to set it up so we can access our accounts from either machine. There are three seperate users.
Anyone know how to set it up to do this?

I can't give SuSe specific details, as I'm working on RH*, and haven't used SuSe at all, but the way I'm working is to set one machine up as a local mail server, run fetchmail to get the mail down from your ISP(s) onto the mail server, then run either IMAP or pop3 on the server to allow you to collect mail from the server from any of the local machines.
This also gives you the chance to run procmail on the incoming mail to the local mail server to weed out any spam, and your local users can use any client such as KMail to collect the mail from the local server ... they will only appear to have a single account on the server though, and would have to sort mail on their client if they want to see which item comes from with of their internet accounts.
However, there does remain the problem that if they set their client up on different machines to erase the mail from the local server's pop3 system after downloading it to their local machine, you'd get the situation where their mail is spread out over several local machines ... consider setting the network up so that the server also acts as a file server, and your users' /home directory is on that server ... this means that the local copy of the mail they have downloaded to their mail client will remain consistent ... and have the advantage that they always have their own settings whichever machine they log on to.

Alternatively, maildrop has .mailfilter files that actually make some sense without a codebook.

If reading from many systems is important to you, it's probably a good idea to use an IMAP server and an IMAP client or use the mailsync program with a normal client.

Thanks, I'll take a look into this.

Another little problem I've noticed is that all the fonts appear squashed in in any Word Processor I load. Admittedly this problem is not as bad in SuSe as it was in Mandrake, but I was wondering if there is a way to correct this problem?

Can you send us the "Font Path" part of the output of the command "xset q" and maybe upload a screenshot (gimp: File->Acquire->Screenshot) of the problem to your web space? It might be that you need more fonts, or that the system has "lost" your fonts.

I'd recommend that you use postfix (plus Courier IMAP/POP3) with spamassassin and sophos/NAI anti-virus, the set-ups for which are well-documented. We use all the above and are very happy with performance, flexibility and the ability to automate installs. I've used procmail recipes for anti-spam, and they are simply ineffective against most spam these days. To be specific, most spam is now in MIME format, and/or html, and in the latter case, spam trigger words, like FREE are rendered as FR<!--- xxx --->EE in the html, causing procmail to miss them. No doubt a procmail wizard will tell me I'm wrong, but life's too short when there's a tool like spamassassin which sorts it all out, unpacks zips et al, undoes and examines MIME, and defangs html.
Cheers, Laurie.

spamassassin I found to be rather memory and CPU hungry and not particularly effective against the spam I get. I currently run a 3-line defence:
1. I can't read Chinese or Korean, so most of that is filtered out. (Sorry.)
1.5 List emails get filtered off here at present. ;-)
2. A Distributed Checksum Clearinghouse filter (dccproc) filters off most bulk mails (nb, that is not quite the same as spam, but close enough for most).
3. A slightly under-trained (1500 emails seen in total) Bayesian word probability filter gets the rest.
I get about 2 spams in my inbox per day, on average, which is a false negative rate of about 0.2%. I haven't had any non-spam non-bulk email in the spamtrap yet.

What methods programs etc. do you use for all of these? homebrewed or does it come from somewhere else? It would be interesting to know as I have been running spamassassin for nearly a week and it gets too many bulk emails that I actually want to receive (and remembering to add everything to whitelist every time I subscribe is a pain) and is still letting through quite a few spams.
I want to look at alternatives anyhow before I go through and actually configure spamassassin a bit more...

maildrop does most of the filtering through other programs, passing off to list mailboxes (via some homebrew scripts on my web site), etc. It should be in most distributions, I think.
dccproc does the DCC part and can be downloaded in source form from http://www.rhyolite.com/anti-spam/dcc/ -- I call this via maildrop's xfilter command, like so:
xfilter "/usr/lib/dcc/dccproc -h /home/markj/.dcc -S List-Id -c CMN,5 -w email-whiteclnt || /bin/true" if (/^X-DCC-.*-Metrics:.*bulk/:h) { to $MAIL/spamtrap }
The Bayesian filter is a fairly straight homebrew implementation of http://www.paulgraham.com/spam.html but there are others out there. Avoid Bogofilter, as it's fairly poor. "Bayesian Mail Filter" (the literate programming one) is a better one. If people want, I can try to offer source and static binary of my homebrew. It's called in a similar way to dccproc.
Is that all of it?
If you are running Sendmail, you can do a lot of spam filtering righ there. Build your sendmail with REGEX enabled, download and configure the check_local hack from the sendmail website, and off you go. As a sample, here is my Sendmail config
divert(0)dnl VERSIONID(`@(#)generic-linux.mc 8.9.5') OSTYPE(linux)dnl DOMAIN(generic)dnl
define(`confTO_QUEUEWARN', `24h')dnl define(`confPRIVACY_FLAGS', `authwarnings,noexpn')dnl
FEATURE(`use_cw_file')dnl FEATURE(`relay_entire_domain')dnl FEATURE(`access_db')dnl FEATURE(`dnsbl', `spews.relays.osirusoft.com')dnl FEATURE(`dnsbl', `spamhaus.relays.osirusoft.com', `Open spam relay - see http://www.spamhaus.org%27)dnl
KContentType regex -a@MATCH text/html|multipart/(replace|alternative) HACK(`check_header', `Content-type', , `ContentType',,,,,0,1, `MIME messages not accepted')dnl HACK(`check_header_end')dnl
MAILER(local)dnl MAILER(smtp)dnl
This checks for known spammers and open relays, and reject pure MIME messages, such as are sent by spammers and hackers.

Aside from the advice already given, you'll need the box to act as a router for internal traffic through the ppp device. Take a look at the SUSE firewall which has a nice GUI, and appears to be easy to set up. I don't use SuSE any more, so I'm not much further help!
Cheers, Laurie.
