Like all SecurityGateway releases, the developers at Alt-N continue to add new customer requested features and enhancements. Here is a quick overview of just some of the features end users and IT administrators will find helpful. A more comprehensive list of all new features and enhancements can be viewed in the SecurityGateway for Email Servers Release Notes.
Added Support for DMARC (Domain-based Message Authentication, Reporting, and Conformance) to enable domain owners to direct the actions to take when handling messages purporting to be from their domain(s) but were not actually sent by them.
The web interface has been updated to use a mobile first responsive design that is based entirely on the size of the screen being used. Whether the user is on a phone, tablet, or PC, the appearance is the same for the various screen sizes.
For servers that have multiple IP addresses, each domain can now be bound to a specific IP address. Mail from the domain will be sent from its assigned IP address.
