Anti-Spam

Our anti-spam service typically blocks 99% - 99.5% of spam, and is very unlikely to block legitimate email. Besides the obvious, time-saving benefits of stopping spam, additional benefits include:

Stops 99.5% of All Spam

With the initial default settings, wisnet.com's Anti Spam for Exchange will "out of the box" block 99% of all spam for most customers. We believe it is actually very close to 99.5%. (I.e. we block 199 out of 200 spams.) If the Realtime Blacklists (RBLs) and Country Filtering are disabled, our service will still block 98% of spam; in this mode the false-positive rate will be less than 1 in 100,000 (i.e. 99.999% of legitimate email will pass).

Depending upon the security of your mail server, the perceived spam blocking may be less, because some spam may be able to bypass our service. Ideally, if you have an in-house mail server and set a firewall to only accept email from our service, no spam can bypass our service, and over 99% of spam will be blocked.

If your email is hosted at an ISP or outside hosting company, the perceived spam blocking may be only 95%. Most of the remaining spam will actually be bypassing our service due to tricks that spammers use. If your ISP (Hosting company) supports "optimal MX records", you can reduce the spam which bypasses our service and thereby typically block 98-99% of all spam. (In-house mail servers should also use the optimal MX records.)

Reducing spam increases productivity and morale. By industry estimates, each employee spends over an hour a month just deleting spam; many are also deeply offended by its content. As more employees receive email on remote laptops, PDAs and pagers, it becomes even more important to stop spam.
