Re: Postfix trouble
Others will have better insights, but you might consider configuring
postfix to require authentification before sending mail:
You might trim $my_networks to NULL
You might configure something like amavis/clamav to virus check your
mail. (though this will do nothing for your SPAM)
You might get agressive about checking your logs and assist your users
in virus removal, or use something like iptables to deny access to all

I need an advice on the following problem:
I setup an email server for a small ISP. The server is sarge with
postfix as MTA. Unfortunately some of the clients contacted a
virus/spambot that is sending spam via my mail server. I want to bloc
spam that came from $mynetworks but the sender in not in $relay_domains.
Is such thing possible ?
Thank you in advance !
