POP3 Gateway for Microsoft Exchange and Lotus Domino with Anti-Spam Filter and Anti-Virus Protection

Incoming mail transfer	Any number of POP3 mailboxes par user. Any number of users per POP3 mailbox. Supports automatic mail routing for multi-user POP3 mailboxes (catch-all mailboxes). Automatic mail routing using visible or hidden message headers. If relevant information is available in hidden message headers, you can reliably achieve automatic mail routing even for BCC-addressed messages. Supports multiple users for a POP3 mailbox with a single SMTP address. Optionally can leave messages on the POP3 server after download. Useful for roaming users, or people who read their mail from more than one location. To keep the POP3 mailbox tidy, messages beyond a certain age can be removed automatically. Automatically remove certain unwanted message headers. This feature is useful to avoid automatic read receipts which would otherwise be sent by older Microsoft Outlook versions. Supports automatic notifications to the sender of an incoming message in the following circumstances: - a message is sent to an unknown address in your messaging domain, - a message is sent to somebody who left your organization. In both cases, the templates used to construct the notification messages can be customized. Write a log entry for each message.
Content-checking of incoming mail	Anti-Spam analysis with SpamAssassin (an award-winning open source spam filter). Check the contents of messages : define a set of rules to determine which messages should be intercepted, or which messages should not be intercepted (this is useful to define exceptions with respect to other rules). Check for attachments, active content in HTML messages, the sender's name or address, or words in the message subject. For each rule you decide what should happen: send a notification, the message, or the encapsulated message to the destination and/or other destinations. Or send a customizable notification back to the sender of the message (this can also be used to make an auto-responding system). Or just delete the message. Scan messages for viruses: use a file-based real-time virus scanner, which may already be protecting shared folders on one of your file servers.
Outgoing mail transfer	Add a disclaimer to outgoing mail. Allows you to have several mailboxes on your mail server with the same sender's address appearing on the Internet. Rewrite the real name part in the sender's address for certain sender addresses. Have control over who may send mail, and which size limit applies. Use a SMTP relay server which requires authentication before mail can be sent. Or connect to a POP3 account before sending mail (POP before SMTP), Archive outgoing mail. Write a log entry for each outgoing message. With expensive dial-up Internet connections, collect several messages before sending them all at the same time, to keep connection charges low.
Scheduling	Collect incoming mail regularly. You may exclude non working hours and non working days. Out of schedule connections can be triggered using the included Remote Control program. This can be done from any machine in your LAN. No tricky operations are required to download urgent mail immediately. Supports different strategies in outgoing mail handling depending on the priority and size of outgoing messages. With a permanent Internet connection: outgoing mail may optionally stay in the queue for some minutes, so it is possible to intercept it if needed. The time interval can be configured depending on message priority, A dial-up Internet connection can be established when needed. To keep connection charges low, incoming and outgoing mail transfers are synchronized.
Configuration and administration	A Configuration Wizard guides you through the most important configuration issues. Real time supervision of mail transfer activity, with the included Remote Control program. Runs as a Microsoft Windows service. Many built-in diagnostic tools will assist you in troubleshooting, should ever a problem occur. Simulation tools let you immediately check how an incoming message constructed on-the-fly would be routed, or how content-checking rules would act upon a message. Interfaces to the various mail servers are clearly defined. Only standard Internet protocols, such as POP3, (E)SMTP and LDAP are used.
Requirements	You need an internal mail server, such as Microsoft Exchange 2007/2003/2000/5.5, Lotus Domino or any other mail server being able to receive messages with SMTP. PYTHEAS MailGate uses standard Internet protocols (SMTP or ESMTP, LDAP) to communicate with this server. The PYTHEAS MailGate Configuration Wizard has special support for Microsoft Exchange 2007, Microsoft Exchange 2003, Microsoft Exchange 2000, Microsoft Exchange server 5.5 and Lotus Domino server (R5 / R6 / R7 and R4 since version 4.6.1).

The product runs on Microsoft Windows Server 2003/2008/2000 or Microsoft Windows XP/Vista/2000/NT, to make it short, on a i386 platform (32bit/x86 or 64bit/x64). It should also run on Microsoft Windows 95/98/Me. PYTHEAS MailGate can run as a Microsoft Windows service (and we recommend to install it as such).
