The Email appliance is reliable, easy to maintain, and works as advertised. However, there are always issues with technology and support is needed. This is where Clearswift shines. The support team has always been prompt, professional, and had the right answers. This is the Triple Crown for support teams.

The Email Appliance has rock solid reliability and with online system and content rule updates, the overhead of running this SMTP gateway is incredibly low. The logging is excellent and provides a positive answer on what happened to every email that has been processed by the device.

Ahsan Bhatti
Team Leader Messaging, Fujitsu Australia and Newzeland
I would strongly recommend the appliance as it is very easy to setup and configure. The interface is very user friendly and provides all the necessary features required in the mail content filtering software. The pre and post sale support is fantastic. Also the license cost is great compared with the competitors.

MIMEsweeper means that the appropriate technology is in place to recognise, report and act on any issues that arise in this area.

We had been looking for an anti-spam solution that would effectively protect us from flooding spam, globally and selectively using various criteria. MIMEsweeper fulfilled all our expectations with additional security layer and effective email traffic analysis.

MIMEsweeper is easy to manage and maintain; the spam filter is scalable and we appreciate the LDAP integration. All in all Clearswift offers a good cost/performance ratio.

Rob Grandcourt
, Sunshine Coast Regional Council
We needed a robust, reliable, flexible and scalable solution to handle increased email volume with varied policies. Clearswift Mimesweeper Email Appliance provides the solution. We also chose to use the Mimesweeper Web Appliance, rather than other products previously in use at our sites. A simple interface and easy configuration, increased speed and better malware protection, plus the 'easy for management to ratify' concept of categories in the URL Filter allow effective policy enforcement. IT staff acceptance of the product has been very good. Both products are helping us build and maintain the high quality and agile IT infrastructure demanded by our business as it becomes one of Australia's largest and best Local Governments.
