Thanks Ken, writing a custom function would be greek for me.. though the 
list archives did return some simple examples.

The original idea was to scan outgoing authenticated mails for viruses 
and policy violations but skip spam checking (based on the presence of a 
X-Auth-Header)..

We've been doing this using separate servers so far, but for a new low 
volume customer, i can't justify investing in 2 servers and will have to 
do with one server for both incoming / outgoing.
