I have various business email addresses, just to keep different aspects of our business separate. Increasingly I get more and more spam, and was interested in knowing if anybody uses a spam killer program that they like that works with multiple email addresses.
I use Mcafee spamkiller. It seems to kill a lot of spam (376 messages in one month from one email address). It has a learning function, updates and you can add your own filters. It is not perfect and not free but I am happy with the purchase.
