Prevent amavis from obliterating spam headers

[Quanah Gibson-Mount]

Hi,

Customers who have external scanners running SA prior to hitting Zimbra's 
SA install have found that Amavis will obliterate existing SA headers. 
Additionally, redirecting an email that was previously scanned by SA also 
results in Amavis obliterating the existing SA headers.

Is there a method in which Amavis can be configured to preserve existing 
headers?

reports.

Thanks,
Quanah
