upgrade amavisd on Dapper 
Do you get a message like this after a Dapper security update:
/etc/init.d/amavis start
Starting amavisd: Found old config file /etc/amavis/amavisd.conf,
amavisd-new will NOT be started for safety reasons.
Please update the amavisd-new configuration, as the
old configuration is not automatically converted.
Remove the /etc/amavis/amavisd.conf to re-enable amavisd-new.
When i looked /etc/amavis, I see a file:
amavisd.conf.disabled
Should be disabled right? Apparently not. I just moved it out to /root, and then amavis started up using the new configuration in /etc/conf.d
