    Have you turn on SpamAssassin?

    Do you have control over the mail server? If yes, turn on RBL also. :D

    since the original question states NO operating system and NO MTA
    I safely assume Linux and Postfix

    spamassassin certainly is an option
    but there are more basic options that might come first
    provided you are on a root server and have your system unter full control.

    if you have NO root server - then that spam might simply be the price to pay for having NO full control over your server.

    as root on your machine - Postfix has some 100+ configuration options that help you to exclude most of all spam before it even reaches your server or mailbox.
    see
    http://www.postfix.org/postconf.5.html

    a key to success is the full use of server auth requirements. a spam server often has inadequate configuration settings or fails to properly authenticate when connecting to your server ( more precise MTA ). like for example no DNS resolving for the senders IP or no valid senders FQDN

    by requiring full precise auth before accepting mail,
    by accepting mail only for accounts actually existing,

    typical postfix parameters to look at or to add to your main.cf would be config options dealing with

    body_checks
    smtpd_recipient_restrictions
    smtpd_sender_restrictions

    myself I have an average of some 500 mails per day
    that pass the postfix filter
    and out of that large number only about 10-20 spam mails each day drop into my actual mailbox - all others are filtered by my mail client evolution.

    without postfix filters I had 2 times and more

    another essential point of configuration is to remove a catch all configuration and replace it by precise accounts actually existing.

    in my earlier hosting config i first used a catch all - by replacing "catch all" with requiring verification of existing reĉipient account, the spam quantity dropped instantly to a fraction of original number.
