Zaep can function as a plug-in for MDaemon 8.0's new plug-in architecture. When installed as a plug-in, Zaep's anti-spam capabilities are not tied to a specific mail retrieval protocol enabling users to experience a spam-free inbox whether they use POP3, IMAP, or their browser to retrieve their email. Additional benefits of running as a plug-in include tighter integration with the mail server, immediate challenging of unknown messages, and limiting Zaep support to specified local mail domains. Plug-in support for Zaep is included with both Zaep Home and Zaep Professional editions.
