Read Alt-N's published white paper on DKIM and its implementation in MDaemon at http://www.altn.com/support/white_papers.asp. In addition to DKIM, MDaemon 8.1 includes support for Greylisting, a relatively new spam fighting technique which involves deferring the initial acceptance of a new mail message from unknown senders and tells the sending email server to try again later. When the sending server tries a second time - which most spam sources will not do - MDaemon will accept it. Exception options and white lists can exempt trusted senders from greylist processing. MDaemon 8.1 builds on the groupware, security and administrative improvements made available with MDaemon 8.0. MDaemon now includes free groupware functions, including shared calendars, contacts and task lists. It also continues to lead the industry in email security, professional fine-tuning and beginner ease of use.
