Can someone recommend the best anti-spam approach and email service/software? - mailshell anti spam software

I was a service user care consumers Mailshell replaced later this month. The most popular is the e-mail non-returnable. Power bounce only an e-mail once it had been sold, the most effective for me. I have never used a spam and off only once before spammer addresses addresses good intentions, sometimes even legitimate businesses. Never did care about false positives or ask people who wanted to correspond with the recording.

Perhaps sensing technology over the years improved?

I am aware, addresses four techniques, filters, black lists, records, and disposable.

Everyone wants to recommend a better alternative for me? I am willing to pay for the service. It must be stable (no crashes) and professional (no added advertising to e-mail, etc.
