MDaemon , Windows-based email server software, contains full mail server functionality and control with a strong emphasis on security to protect your email communication needs. MDaemon features include top-notch antispam security features; seamless integration with AntiVirus for MDaemon plug-in; built-in groupware functionalities for sharing folders, tasks, contacts, and address; separately licensed plug-in for Outlook users to access groupware functionalities using MDaemon as the mail server and groupware platform; secure instant messaging; free web-based email client; remote administration tool; central address book repository; and much more! MDaemon 8.1 new feature includes the first implementation of DomainKeys Identified Mail (DKIM) for the Microsoft Windows platform. DKIM validates the sender address and message integrity of each email received. MDaemon creates outbound signatures and validates inbound messages signed with DKIM. 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.

AGAVA AntispamServant

AGAVA AntispamServant is a trainable filter featuring message content analysis. AntispamServant is characterised by high-speed and efficient operation with all e-mail clients, and does not require them to be specially adjusted. AntispamServant is analysing the spam and non-spam message samples you provide, developing sorting algorithms on the basis of the user’s criteria and constantly updating the whitelist, which ensures almost 100% efficiency in identifying unwanted mail. AntispamServant does not delete e-mails identified as spam messages but moves them to a separate folder. You can check the contents of the folder any time later instead of checking new received messages every minute. The spam filter is devoid of the problems common for the majority of baesian filters. AntispamServant: - applies a complex formula to deduce the summarized spam coefficient of the e-mail messages, thus preventing the problem of short-cut calculation; - accounts for the human error factor in the course of the training process and provides opportunities for subsequent correction; - is protected from over-training, as it is trying to classify e-mails before analysing them as samples; - uses an HTML parser to prevent the influence of common HTML tags on e-mail classifications; - identifies functional parts of speech and excludes them from calculation, so as not to degrade the quality of filtering; - can successfully classify e-mails even on the basis of short headers containing 2-3 words only. Other advantages of the program are that there are no restrictions on the number of mailboxes being filtered and that you can simultaneously use any other spam filters. AntispamServant supports POP3, IMAP and SMTP. This antispam program automatically identifies and supports SSL-connections.
