Disclaimer variables passed from amavis to altermime.

[Frank - WarrantyTree]

I am running a basic iredmail install with amavis, postfix, dovecot.
I want to use the declaimer feature to automatically append a disclaimer (in
our case a signature).
The reasoning for this is that clients (ipad, outlook, etc) don't have to be
configured with signature settings, and that we have corporate control over
the actual signatures that are posted.

Instead of:
'boss at domain.com' => 'boss.domain.com.txt'

I am trying to get to 
%mailbox + '@' + %domain =>  %mailbox + "." + %domain + '.txt'

This way we can simply use a script to generate the .txt / .htm signature
files using just mysql / php.

THANKS IN ADVANCE
