    I'm using posftix+amavis+ polish (mks-vir) for virus scanning

    pop-before smtp + ordb + few others db + local regexp database for stop
    relaying and anti spam.

    The result in relaying is 100% accurate, but spam is comming from time to
    time ( eg. V1@GRA).

    But where my problem is:
    My problem is with my local users (about 3k LAN users in about 500
    buildings), they send spam (viruses, worms etc) not using my MTA.
    I'm looking for transparent method (like redirect for transparent-proxy
    w3cache, squid) to force traffic on port 25 to go via my MTA.

    Do you have any ideas or experiences with that ?

    I thought about writing own code for that, but im far far away from that
    (begging with C proggramming and kernel hacking), instead i'm good in mixing
    every working capabilities wich are accessible and done before by somebody
    else ;)

    BTW.
    Well, if somebody is wondering how such LAN can work with linux routers +
    sql_db + local_scripting + php + bash = CRM and NETWORK_ADMINISTRATION,
    BILLING_SOFTWARE, AUTOMATIC_EMAIL_OFFICE visit my own software (sorry - but
    is not in english and has 1mega pictures) http://nsm.pl/~arek/superedit .
    I'm interested in sharing my soft for development purposes or any other.
