Using an RBL is definitely the way to go. I only use Vispan for the
graphing as I found it making our access file huge and using way too
much CPU time inserting and deleting entries in the access file.
I ended up writing a custom function for MailScanner to log spam
messages into a database and then generate files for rbldnsd using that
information.
