Per User

[Duane Hill <d....@yournetplus.com>]

We have a server that is filtering inbound messages destined for our 
internal email server. Other than SMTP verification to the internal 
server, the filter server has no knowledge of account existance.

This filter server is running Postfix and I am able to send to spamc the 
user name. However, logs show this is not working because the user name 
does not exist locally:

   handle_user unable to find user: 'example@example.com'

and it falls back onto the user name 'nobody'.

By the time the message is scanned by SpamAssassin, the recipient has 
already been verified to exist.

Is there a way I can get this to work? If this has already come up, point 
me in a direction.
