Phishing

[Pramod Daya]

I'm having problems with phishing scams getting through - have installed ScamNailer 2.10, with the cron job running successfully, hourly, and also downloading the scamnailer.ndb file from www.mailscanner.eu (Should I be doing that as well as running the cron job ?)

Most are trapped, but enough get through daily that I'm sure it can be improved.  Can one expect 100% of phishing to be stopped, or is that an unreasonable expectation ?
