Osmosis Spam Blocker is an application which will block unwanted mail. Its operation can be compared to physical phenomenon of osmosis, in which a semi-permeable membrane acts as a filter eliminating impurities. Key advantages: 1. Osmosis Spam Blocker will never reject a correct e-mail - the likelihood of such is 0,00%! This is possible due to the fact that Osmosis Spam Blocker does not scan the content of an e-mail. It applies different criteria for sorting e-mails, which allows for a great degree of accuracy. 2. Spam never reaches the server, does not load the internet connection line or the server itself. Unwanted mail is rejected before it reaches the server. 3. Osmosis Spam Blocker is easy to install and use! It only needs to be installed once on your server - afterwards, the application operates automatically. It does not require any set up configuration. It is extremely easy to use, both for system administrators, and for mailbox users.
