SPAM Filtering/Blocking & Antivirus Services :: SPAM & Antivirus Home

Designed for the small to medium sized business who wants an instant, low-management solution to the ever growing problem of SPAM. ISG updates our SPAM and Antivirus patterns/filters every hour 24X7X365. SPAM filtering/blocking results have proven to be 97% effective or higher! Got Exchange?

The ISG Spam Blocking service learns on a user by user basis, in turn creating per-user quarantines and settings based directly on the web driven feedback from the end users. As a result this solution is the most effective while minimizing the possibility of 'false positives' (i.e. blocking mail the user wants). This solution is ideal for network administrators as well since the solution interacts directly with the end-users in straight forward and easy to understand methods.

ISG offers the following plans based on the number of accounts protected. ISG sells our SPAM blocking and Antivirus services in blocks for non-existing clients and per domain for existing web hosting or standard email hosting account clients.

MS Exchange Accelerator

The ISG Advanced SPAM Blocking service can significantly offload an existing Exchange server and free up system resources by verifying the existence of each email recipient via a simple LDAP query prior to delivery! Messages to non-existent or invalid email addresses are dropped and your server never has to deal with them.

Explanation:

A "Dictionary" or NDR (Non-Delivery Report) attack is a sequence of spam messages that attempts delivery to every possible recipient name on a server. Microsoft Exchange attempts to protect against "Dictionary" attacks by accepting messages for all recipients rather than rejecting invalid recipients and letting a spam sender know which accounts are valid. Unfortunately, this often leads to very high Exchange server CPU loads because the server still attempts to send one or more non-delivery notification for every invalid recipient.

The MS Exchange Accelerator uses the LDAP service built into Exchange to verify recipients before delivering messages to the MS Exchange server and consuming valuable resources. This premium service is recommended for all MS Exchange configurations.

Note: The LDAP protocol must be enabled on your Exchange server in order to use the MS Exchange Accelerator. LDAP is automatically on by default in most MS Exchange installations.
