Using DomainKey and Sender ID as an end user

Most implementations for using DomainKeys (or DKIM) and Sender ID are written and used on the level of the MTA to verify the authenticity of the message.

Now iconix has written a piece of software which allows the verification at end-user-level. That allows them to bring the whole process and system behind DomainKeys, DKIM, Sender IDs, SPF and so on from the MTA level to the end-user and in this case allows a broader mass to use the feature.

The tool has still some hick-hacks but its working quite well and the developers trying to fix problems as fast as possible. There are a lot of implementations available at the moment, for different mail programs as well as webmail systems.

If you wanna use one of the above features in your mail environment please don’t hesitate to ask the internet or drop me a message, especially if you are also one of these guys trying to give SPAM no chance. And most important,  if you are using one of the incredible Ironport C-Series machines, setting up DomainKeys or DKIM verification is only a few clicks away 😉
