Vanguard provides enterprise class anti-virus and anti-spam protection to multiple internal mail servers, including the Gordano Messaging Suite, Microsoft Exchange, and IBM Lotus Notes/Domino. Dual anti virus scanning engines provide both traditional signature based virus protection and advanced Zero Hour protection. Any number of internal servers can be protected from a single Vanguard server. Each of those servers may be servicing the same Internet domain, separate Internet domains, or even multiple Internet domains on a single server. There is no limit to the number of protected domains or message throughput.
hermes is a generic, transparent and multi-platform anti-spam SMTP proxy that uses a combination of techniques (like greylisting, throttling, DNS white/blacklisting, SPF, etc.) to stop spam from reaching your mailbox. Many mailboxes see a 98% spam reduction with no false positives, as hermes is not filtering email based on content, but on strict adherence to the SMTP standards. It's also compatible with most SMTP extensions like STARTTLS (for SSL security) and SMTP-AUTH (for user authentication).

Mailonator is a system that guarantees the delivery of email attachments quickly and securely and avoiding any restrictions that might be in effect for the email recipient. Mailonator software installs on a server, so the email service and client tools never need to change. It works by intercepting email messages, stripping the attachments, and storing them on a server. In addition, Mailonator sends you an email notification when recipients download your attachment, and provides system administrators with usage statistics.
HashCash is an anti-spam, anti-DoS system for email. The concept centers around the sender of the mail completing a computationally expensive task (in this case, generating hash collisions) that the recipient can verify very quickly. This allows the sender to "pay" for transport in CPU cycles, creating artificial scarcity. Programs are included to add payment to messages (for the sender) and to verify message payment (for the recipient).
SPF is a new strategy for preventing junk mail. The present SMTP standard for email allows anyone to forge anyone else's email address. SPF verifies that the Sender address of an email message matches (according to some policy) the client IP address that submitted it. libspf2 is a complete and robust implementation of SPF which provides support for many MTAs. Support for new MTAs is in progress.
