Hi I'm installing a brand new mailserver, and I'll use postfix + ldap + courier + amavisd-new + spamassassin + razor. (Here you can comment if you think this decision is correct :P) Now I'm deciding if I'll use also DCC (Distributed Checksum Clearinghouse), but I don't know it very much, and besides it don't has any debian package, so I'm not sure at all... Any of you has any experience with DCC?
