SpamTitan Gateway is standalone so there is no cloud dependencies, very good layout and intuitive. SpamTitan works as advertised in removing 99% of the spam virus’s and malware. Installation takes minutes with minimal configuration. However, it also allows for a wide variety or customizations. The support is outstanding.
One of the companies that we deal with has had the same domain name for close to 30 years and have used their email addresses for personal as well as business purposes as a result they receive a higher than normal amount of spam. Spam Titan has managed to all but completely eliminate that problem.
I would recommed that you have about an hour of free time to install this product. The help department when confirming your installation are thorough to a fault.
