I've just configured the amavisd-new-snmp package from Amavis 2.6.4-1 on 
Fedora 12 and works great. It's surely good to have SNMP statistic 
features in Amavis and 
hope, that the amavisd-new-snmp package will be included in the Scientific 
Linux. I don't know, why this is still unincluded in scientific linux 
and so I ask if there is any plan to include it?

Best regards, Tomas
