A business owner who needs a stable, robust, easy to use and powerful tool for spam protection does not have much options. Even though the members of his information technology department will probably end up installing and making the actual purchase, it helps decrease the surliness of such staff if the owner does his homework before making such suggestions.
For a business large enough to need a client-side installation rather than a sever side installtion could do worse than Astaro Mail Security. As with similar programs, a person must by a license based on the number of users, but a business can try the software before making a commitment. The owners of the company issued a 30 day free trial to users who do not know if the software will meet their needs.
The features are similar to those in other e-mail programs. The program will scan viruses for attachements, it can block certain addresses, and it offers encryption to the user. Encrypting data is a step many other similar programs do not offer. No one wants sensitive data to get into the wrong hands before it is released.
While the program gives the network administator a good deal of control over the settings, there are some things that are better handled at the level of the individual user and the program takes this into account as well. An individual user can tweak the mail settings for his inbox to suit him. Astaro’s Mail Security is one of the more versatile spam protection programs available today.
