postfix filter function with amavis smtpd-proxy

[support at mmarzouki.de]

hi patrick,

thanks a lot. this was thats the right direction.

but @author_to_policy_bank_maps needs a correct DKIM signature. i found the solution with @whitelist_sender_maps to allow all spammail from any senders. is this okay?

i saw in my lab, that the @whitelist_sender_maps is only for spam, but a virus is blocked.
how can i pass a virusmail from any sender? 

cheers
