What is IMail Server? is a comprehensive electronic mail solution designed for today s evolving Internet and corporate intranet messaging requirements. Easy to install and administer, significantly reduces both the initial cost of mail implementation and the on-going cost of administration. Its easy-to-use features improve productivity and provide a robust alternative to proprietary systems or complicated UNIX-based Internet mail. Introduction provides: Unlimited users OR up to 250 users (depending on license) Full integration with the Windows NT user database Ability to base user mail accounts on an external database A capacity of 250,000 messages a day (tested on a dual processor 120 mhz Pentium system with 64 megabytes of RAM with NT Server 4.0, Service Pack 3.) can be read with: Any POP3 mail client Any IMAP4 mail client Any web browser This Internet standards-based client/server architecture provides system administrators with complete flexibility in setting up a total mail solution that easily accommodates disparate and/or geographically dispersed mail clients. Overview 1

18 Basic Services consists of a number of services that run on Windows NT. The basic service that enables the Windows NT system to receive mail is the Simple Mail Transfer Protocol (SMTP). The services that allow access to mail by client systems are Post Office Protocol Version 3 (POP3) and the Internet Message Access Protocol Version 4 (IMAP4). SMTP Security Support for alternate SMTP, POP3, and IMAP4 authentication methods providing more secure means of sending user IDs and passwords across networks; this allows one of your users to send mail from an IP address that has not been identified to IMail Server Mail relay options: Relay for local hosts only and Relay for local users only Ability to exempt specific address or domains when blocking relays to thwart spammers Ability to disable the VRFY command Support for ESMTP Delivery Status Notifications (return receipts) based on the following: SMTP Service Extensions (RFC 1869), SMTP Service Extension for Message Size Declaration (RFC 1870), SMTP Service Extension for Delivery Status Notifications (RFCs 1891, 1892, 1893, 1894) Support for ETRN host.name and commands (as specified in RFC 1985) Web Messaging Web Messaging allows users to access their mail on the IMail Server system from any web browser on the Internet Web Messaging supports online advertising. This is for Internet Service Providers who want to display banner ads at the top of the Web Messaging mail screens and sell online advertising space on their mail server. Web Messaging administrators can use.html templates to customize, by host, the look of the web pages where users access mail and edit their settings 2 User s Guide

19 Web Messaging administrators can manage virtual hosts, aliases, and list server mailing lists from a web browser Users who access their mail from a web browser can: Sort messages in various ways Maintain an address book Use BCCs ( blind carbon copies ) Establish Sent and Deleted mailboxes Utilize multiple attachments up to a total of 10 megabytes per message Use Delivery Rules and the Info Manager to process incoming mail Manage mailboxes Additional Services In addition to the SMTP, POP3, IMAP4, and Web Messaging servers, IMail also provides the following server programs that run as services on Windows NT: A Lightweight Directory Access Protocol (LDAP) server The LDAP server provides remote access to IMail user information through any LDAP client application. IMail user mail account data includes standard LDAP information such as the user s last name, organization, mailing address, and telephone number. LDAP Version 3 is supported. A list server Mailing lists are used widely on the Internet as a means of sharing information about a topic. The list server lets you set up automated mailing lists; list server mailing lists can receive mail and resend the mail to all the users on the mailing list. The list server also supports moderated and unmoderated lists, as well as the ability to group messages into a digest and periodically send the digest as a single message. The Monitor server provides self-monitoring via a Monitor server that polls each of the IMail services. The Monitor server can be configured to send an , beeper, or pager notification when a Overview 3

20 service goes down or comes back up; it can also automatically restart a service that has gone down. In addition, this server can monitor other services (DNS, NNTP, WWW, Telnet, and FTP), the default gateway, and disk space on either the local or a remote system. You can access the Monitor server remotely using a web browser to view the status of monitored services and perform administration functions. Finger and Whois servers The Finger and Whois servers allow you to publish user information on the Internet. A Password server The Password server lets users of older mail clients (such as Eudora, NuPOP, IMUTIL, and IRADMIN) mail clients change their passwords remotely. For more information on IMUTIL and IRADMIN, see Appendix D. Portable Utilities on page 229. Standard Features In addition to sending and receiving mail, provides a number of robust features. User Registration and Maintenance supports either 250 user accounts or an unlimited number (depending on license); it also supports an unlimited number of user mailboxes. Users need to be registered in order to have a local mailbox and to allow remote POP3, IMAP4, or web clients to connect to the server and retrieve mail stored in those mailboxes. lets administrators: Add, delete, and maintain user mail accounts, standard aliases, group aliases, and program aliases Set up inbound mail Delivery Rules, Vacation Processing, Info Manager automated responses, and Mail Forwarding Update Finger, Whois, and LDAP information Base IMail users on an external database. The basic capability uses the ODBC method, but can be extended to include up to ten different methods. 4 User s Guide

21 Use command line utilities for adding large numbers of users, aliases, and hosts from text files Use command line utilities for deleting old messages Use a command line utility to send a message to all users in a virtual host or on the entire server For more information, see Chapter 4: User Mail Accounts on page 47 and Appendix C. Command Line Applications on page 213. Mailing List Creation and Maintenance You can use to create and maintain list server (automated) mailing lists; these can be either public or private. When a list server mailing list receives mail, it re-sends the mail to all subscribers on the list; resent mail can be sent one message at a time, or it can be accumulated for periodic sending ( digest mode ). For more information, see Chapter 16: List-Server Mailing Lists on page 171. Mail Forwarding You can have IMail forward new mail for a particular user to another address. For more information, see Forwarding Mail to Another User Account on page 60. Vacation Support If a user is unable to answer mail due to vacation or other absence, you can have IMail automatically send one notice to each person who sends mail to that user. This allows people to send many messages to someone on vacation without being flooded with notices that the recipient is away. For more information, see Setting Up a Vacation Message on page 57. Finger Plan Support The Finger protocol is a common Internet tool that allows remote users to see information about users registered on a system. This includes the last time a user read their mail and a Plan file provided by the user that contains any additional information the user wishes to provide in response to Finger requests. For more information, see Chapter 13: Finger Server on page 143. Overview 5

22 Mail Delivery Rules You can create Delivery Rules to direct incoming mail to different sub-mailboxes based on the content of particular parts of a message. Enhanced Delivery Rules which let you scan various parts of a message (To, From, Sender, Subject, entire header, or message body) and re-route the message based on the contents. Delivery Rules can now search for text patterns. You can apply Delivery Rules for the entire server, a particular host, or for individual users. For more information, see Setting Up Delivery Rules on page 68. Automated Mail Accounts The Info Manager feature lets you set up an automated response: when mail is received for a user that has enabled the Info Manager, a prepared message is sent back to the sender. The Info Manager also lets you set up special mail accounts with subareas with unique responses for each sub-area. For example, you could create an info user account for your organization. When someone sends mail to the info account, the system can return a response that describes the sub-areas of the info account, such as sales or classes. Senders can then send a message to info-sales and receive back a message related to sales, or to info-classes and receive back a message about classes you offer. For more information, see Using the Info Manager on page 78. Multiple Host (Domain) Support If you want to receive mail for more than one host on the same Windows NT system, you can set up multiple virtual hosts. For example, if your mail server provides mail service for your local e- mail host, mail.petra.com, and you also want it to provide mail service for another host, mail.acme.com, you can create a virtual host for mail.acme.com. For more information, see Chapter 3: Configuration on page 25. Privacy-Enhanced POP Support Post Office Protocol Version 3 (POP3) is the most common protocol for communicating with a mail server to retrieve messages. The user ID and password are encoded so that they cannot be read by standard text editors. However, the encoding is not complex, and this feature 6 User s Guide

23 should not be confused with security. For more information, see Chapter 9: POP3 Server on page 121. Forwarding of Mail to a Beeper or Pager can route inbound mail to any external program such as preconfigured pager or beeper addresses, or any other application. For more information, see Types of Aliases on page 63. Unknown Local User Processing can perform special processing of mail that is incorrectly-addressed or addressed to users that don t exist on the local host. This is accomplished through a special alias, nobody, which can send mail to a specified program or another user s mailbox. For more information, see Processing Mail to Users That Don t Exist on page 66. Anti-spamming Features s built-in messaging controls prevent unauthorized mailings from using the as a relay or gateway. You can set up the server to accept only mail that originates from local users or that is destined for local users. ( lets you define the systems or address blocks that you want to consider as local.) In addition, you can block incoming messages from specified IP addresses if those addresses have been a source of unwanted . For more information, see Chapter 8: Security and Antispamming on page 109. New in Version 6 Version 6 of offers many new capabilities. User Interface Unified user interface in IMail Administrator that incorporates the former Control Panel Applet, User Manager, Web Manager, and List Server.
