    www.mailscanner.info og spamassassin. This is a very nice program.

    MailScanner scans all e-mail for viruses, spam and attacks against
    security vulnerabilities. It is not tied to any particular virus
    scanner, but can be used with any combination of 14 different virus
    scanners, allowing sites to choose the "best of breed" virus scanner.
    Being open source, site administrators can audit and verify the
    integrity of the system. Its role is a major part in the security of a
    network, and so it must act as a trusted service. The only way to
    achieve the required level of trust is to be open source, an approach
    the commercial suppliers are not willing to take. MailScanner has been
    developed in a world-leading Electronics and Computer Science Department
    at the University of Southampton, and is distributed for *FREE* under
    the GNU Public Licence.

        * Scans e-mail for viruses using any combination of up to 14
    different virus scanners
        * Automatically updates all installed virus scanners every hour, by
    default
        * Identifies over 95% of spam using several techniques, including
    highly advanced heuristics
        * Spam can be tagged, rejected, discarded, archived or forwarded to
    other addresses for inspection by administrators
        * Pornographic spam can be stripped of all graphical content,
    protecting users from obscene content
        * Scans e-mail for attacks against known and unknown security
    vulnerabilities in popular e-mail applications, automatically correcting
    messages "on the fly" whenever possible and quarantining dangerous
    sections of other messages
        * Highly scalable: 1 PC can process over 1.5 million e-mail messages
    per day
        * Robust: Protects itself against "Denial of Service" attacks and
    operating system resource leaks
        * Highly configurable, providing ISP's and ASP's with the
    possibility of using thousands of different rules and configurations for
    any combination of users or domains
        * Easy to set up as all configuration options are supplied with
    "sensible" defaults

Subject: [SLE] Anti-spam software for sendmail relay ?
I am trying to find a freeware e-mail spam filtering tool for a SuSE 7.2
server at work.
I've had a look but none of the ones I've seen seem to be able to cope
with my particular situation.
My setup consists of a SuSE 7.2 box running sendmail which relays mail
to and from another box running Lotus Domino (under W2K). i.e. all mail
sent from the Domino server goes via sendmail on the SuSE box to the
outside world.
Incoming mail comes in from the ISP via POP3 from many mailboxes using
fetchmail. This mail is forwarded to the Domino server via sendmail. No
mail is delivered locally on the SuSE box, sendmail ONLY acts as a
relay.
Spamassassin and nearly all the other anti-spam solutions and how-tos
I've seen all seem to require local mail delivery at the end of the
process. I haven't seen any solutions which can cope with my situation.
I am currently using mailfilter which does catch some of the spam but it
is a very basic solution and I'm looking for something a bit more
intelligent.
Can anyone point me in the right direction ?
TIA
Sean.
