RE: email gateway (transparent) - full transparent

[<arek () chelmnet pl>]

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.
