Up to version 3.30 the following features are available:
- Small and fast: a complete installation of Mercury/32 uses about 1.5MB of disk space, and about 3MB of Windows memory in normal operation. It can sustain throughput of up to 8,000 mail messages per hour on suitably-equipped systems.
- Easy configuration and maintenance through an attractive graphical user interface. You can tell at a glance what any Mercury module is doing simply by examining its history window.
- Mail Filtering: based on Pegasus Mail's industry-leading filtering technology, Mercury provides filtering capabilities on the server platform, allowing you to perform just about any action on your incoming mail (for example, you can set up an address that automatically prints all mail it receives).
- Supports incoming mail via either SMTP, or POP3, or even both: Mercury's POP3 client module can retrieve mail from multiple remote POP3 mailboxes and distribute it to local users; it also supports retrieval and distribution of mail from remote "Domain Mailboxes".
- Comprehensive scheduling manager allows you extensive control over connection times and operation in the dialup environment.
- Extensive statistical reporting - Mercury/32 keeps significant quantities of statistical information about system performance, mail
throughput, security alerts and more. This information can be automatically archived or e-mailed to any address at a period of your choosing.
- Support for specific network architectures via a plugin interface. Plugins are available providing comprehensive support for Novell NetWare Bindery and NDS modes. A plugin is also planned providing native support for Microsoft Windows NT Networks (Mercury will already run well on NT networks, but is not currently able to import the Windows NT user database - you need to create usernames for each of your NT users needing access to mail via Mercury).
- Includes a server module allowing your POP3 users (running Pegasus Mail, Eudora or other mailers supporting the protocol) to change their POP3 passwords remotely.
- Supports automatic replies and automatic forwarding of incoming mail
- Three levels of management for SMTP relaying, allowing you precise control over who can use your server to process mail.
- Powerful mail server handles automatic list subscription and unsubcription, remote file delivery by e-mail, addressbook lookup requests, and remote mailing list management.
- Some of the most powerful mailing list options available, including public and private lists, moderated lists and anonymous lists, all with extensive configurable features. Mercury lists can have practically unlimited numbers of subscribers, and a single server
can manage an unlimited number of lists.
- Daemons, or third-party plugins, can be developed to allow custom automation of any mail process. The Daemon interface is public and includes extensive documentation and source code.
- Includes both Full End-to-end and Relaying SMTP client modules, allowing maximum flexibility for handling outgoing mail delivery.
- Includes support for Authorized SMTP and Authorized POP3 access
- Support for Pegasus Mail noticeboards - have mail delivered to public folders on your server
- Powerful autoresponder features allow you to control the format and layout of automatically-generated messages. You can turn any address on your system into an autoresponder.
