No regrets that we selected this AntiSpam solution
We've just passed the 6 year anniversary with this vendor with no regrets that we selected this AntiSpam solution. The product is great, and Mayflower's customer service and technical support is even greater. For the first 5 years we hosted this on our own servers and as of April 2010, we now send eMail for over 70 of our domains through their 'hosted service'. They filter out what we would have deleted anyway, and it's lightened the load on our servers, and reduced the bandwidth required for inbound SMTP. An excellent feature to flatten our the inbound mail which was growing geometrically!
