I was searching around and I found general items about implementing whitelists for spam... but does anyone know how to implement a whitelist for amavisd quarantined messages? I have payroll emails getting quarantined for "Heuristics.Encrypted.PDF". I need to get these through and this just started with the latest upgrade to 6.0.16...
I was thinking of hacking on the amavisd config file, but I am not sure if/how this gets overwritten by zimbra's config tools.
Any help is appreciated.
