I have a postfix ( amavisd-new, spamassassin, clamav)mx gateway with 5 domains. The message_size_limit is 15M, but one of my clientes needs a conf of message_size_limit=5M(for example).
I know that message_size_limit is a global configuration and i dont want to install another postfix with another configuration at the same machine. Some one told me to use www.policyd.org
. Can i have some examples of configuration? Or another way to do this ?
