"I moved to Kerio Mailserver ... and love it. My customers also love it and it has been a huge success."

"(Kerio MailServer), I feel, has given me a product offering unlike 99% of the web hosting providers out there. My focus has always been on small business and being able to offer email collaboration services vs. POP or IMAP is fantastic."

"Kerio Mail server is by far the best email solution I have used in my 15 years of Net administration. It is easy to install, configure and manage! I am very pleased with the content filtering feature, as it has prevented numerous viruses from arriving in my users' inbox. This is a great value for the investment!"
