Perfectly so! Thank you!

Would it also be possible to load these exceptions (for 
@client_ipaddr_policy and @author_to_policy_bank_maps) from file?

For example we could have a file with ip addresses named 
"client_ip_whitelist":

    10.20.30.40
    10.20.30.50
    10.20.30.60
    ...

and a file for DKIM-signed domains named "dkim_whitelist":

    example.com
    example.net
    example.org
    ...

Would it be possible to load them into @client_ipaddr_policy and 
@author_to_policy_bank_maps respectively? How?

I guess the latter could probably be done like:

    read_hash(\%whitelist_dkim_domain, '/etc/amavisd/dkim_whitelist');
    @author_to_policy_bank_maps = (\%whitelist_dkim_domain);

Would that work?

The former seems more tricky. Any suggestions to read ip addresses from 
file into @client_ipaddr_policy? Would the list accept IPv6 addresses as 
well?

Thanks a lot,
Nick
