With our 30-day trial, you can set up our email filter both inbound and outbound free of charge and without obligation. It even includes the function for legally compliant archiving of your emails. The trial expires automatically, there is no automatic extension!
Please note that DNS entries for your domain have to be changed in order to set up the filter. Usually this is possible via a web interface available at your hosting service provider, otherwise please contact your domain administrator or provider. Further details will be sent to you by e-mail after registration.
