The term of SSL certificates can be ordered individually as needed from our partners D-Trust, SwissSign and GlobalSign. One- two- or three-year certificates had been possible so far. The Certification Authority Browser Forum now has announced that from March 1st 2018, certificates can only have a maximum term of 825 days or rather 27 months. As of today, you should avoid orders with a three-year term. D-Trust has already responded and does not offer three-year certificates anymore. Those that are still in operation are not going to lose their validity.

Many customers ask how to block certain attachments, especially potentially harmful ones. Here is how it works.
First of all you have to define a ruleset which you want to use. We call it a content filter policy. Select Presettings (1) and Add (2) to create a new one. Give your policy a good name for what it will do. Now you have to define the attachment types you want to give a special treatment. Click Add (3) and create a new definition. Please be aware your definitions are evaluated from top to bottom and first matching entry will be applied. So if you allow invoice_0815-GmbH_*.zip this should be on top of rejecting *.zip-entry.
A new update fixing some bugs has been released. We recommend all customers to apply this update. It can be found in our download section.
According to this post, there is a major bug in .NET 4.6 which could have a serious impact on every NoSpamProxy installation. Please do not update to .NET 4.6.
