New MDaemon releaseIt may only be labelled a point release, but version 14.5 is absolutely crammed with improvements, highlighted by the somewhat 'epic' release notes linked below. This release sees the addition of DMARC (Domain-based Message Authentication, Reporting and Conformance) support, which essentially standardises how email receivers perform email authentication using both SPF and DKIM.

As with a lot of new technologies the real power comes from when they are used by the masses. Sender Policy Framework or SPF is no longer a new technology and is generally widely used to help preserve email domain reputation for large organisations, but it's as well-known about in the Small to Medium sized business end of the email market. Spammers know this and have started to target domains that do not have valid SPF records as they can most easily be used to spoof and send spam claiming to be from valid companies. Often these types of spoofed email are used in phishing attacks to then harvest more valuable data, so the smaller companies that can adopt the use of SPF the better.
