I'm not talking about your server. I'm talking about the client. The
first message was sent from a client on a network considered dynamic.
You show this was sent via SASL auth. The second message was sent from
a client on a network considered static. I don't know if this is your
network or not - or if it was sent via SASL auth or not. The basic
problem is amavisd-new needs to know the difference between one of
your clients and all the rest of the clients in the world. You need to
use some means of differentiating between the two. Policy banks is one
means of doing so. Read through the link I gave you. It shows one
example of the MYNETS policy bank, which can be used to override
amavisd-new settings for clients on your network. And it shows how to
do the same for clients using SASL. It also shows other ways of
lowering the SpamAssassin score for SASL auth clients. See also:
