> Hello Mark,
> I'm a little uncomfortable with the DKIM check implemented in amavis.
> For unrelated reasons we use an spf-milter and opendkim-milter in
> front of amavisd-milter.
> So in the moment amavisd-milter get the message there are already
> two A-R Header present.
> Unfortunately amavisd-new could not "use" the results but has to
> verify the DKIM signature again.
> There is an option $enable_dkim_verification which could be 0.
> In that case SA itself verify the DKIM signature but that fail for
> large message
> (larger the $sa_mail_body_size_limit) as they aren't fully visible to SA.
> As a result we must do the DKIM validation twice which is a wast of
> Feature Request: Amavisd-new should recognise A-R header and use/trust them.
> Assumption: the A-R header aren't present in an incoming message but
> really added by a local milter.
> The milter we use make sure present A-R header for a given
> AuthservID *are* removed.
