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.

Anti-virus Scanning

Anti-Spam for Exchange will scan email attachments for viruses and remove infected ones. A scan summary is added to the bottom of the email message, before the attachments.

Ideal for any Business
Exceptional accuracy, especially in not blocking legitimate emails, makes it ideal for any business. It will not block legitimate newsletters from banks that contain mortgage offers, or any of the other types of newsletters that are often blocked by other anti-spam systems.

Our Anti-Spam for Exchange (Email Gateway Protection) is even suitable for medical and legal organizations that must allow emails with any content. Since our Anti-Spam for Exchange does not block spam by using "trigger" words or simple phrases, it will not block legitimate emails even if they contain medical words such as "viagra", sexual or criminal phrases, etc.

Increase Your Email Relaibility

You may understandably be concerned about blocking that one-in-ten-thousand email from an important prospect. Our service actually reduces the chance that you miss any email. This service uses two "relays" which will spool (i.e. "save") your email messages in the event your mail server is off-line due to power failure, system email crash, routine maintenance, a fiber cut, or any other reason. When your mail server is back on-line, it will automatically receive the spooled email. (Our service will spool your mail for up to five days.) During the blackout of 2003, not one of our customers in the blackout area lost a single email.

Even assuming a worst-case scenario that our Anti-Spam for Exchange blocks 0.1% of legitimate email, then doing the math, if your mail server is off-line for just one hour a month (e.g. for update patches), SpamStopsHere actually increases your email reliability. Since a typical ISP's email system is down for several hours each month (more than they like to admit), our service will greatly increase your reliability.

This valuable service is sold separately by other companies by the name "E-mail backup" or "Store and Forward"; it is included here at no additional charge. This service benefits your IT department since they can now take your mail server off-line for routine maintenance, updates, etc. (It is very likely that your IT department or hosting provider takes your mail server off-line regularly without informing you. During this time, your email is lost.)

Our two relays are located at different data centers for complete redundancy and reliability.

In summary, the reliability of your email is our primary concern.
