Additional Services
In addition to the above basic servers, IMail Server also provides the following server programs that run as services on Windows NT/2000:
- A Lightweight Directory Access Protocol (LDAP) version 3 server
The LDAP server allows remote access to IMail Server user information through any LDAP client. IMail Server user data includes standard LDAP information such as the user's name, organization, mailing address, and telephone number. For more information see "Chapter 12: LDAP Server".
- 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. For more information see "Chapter 17: List-Server Mailing Lists"
- The Monitor server
IMail Server is self-monitoring via a Monitor server that polls each of the services. The Monitor server can be configured to send an e-mail, beeper, or pager notification when a service goes down or comes back up; it can also automatically restart a service that has gone down.
In addition, you can use this server to monitor other services (DNS, NNTP, WWW, Telnet, and FTP), the default gateway, and disk space, from 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. For more information see "Chapter 11: The Monitor Server".
- Finger and Whois servers
The Finger and Whois servers allow you to publish user information on the Internet. For more information see "Chapter 15: Finger Server".
- A Password server
The Password server lets users of older mail clients (such as Eudora and NuPOP) change their passwords remotely.
- Queue Manager service
The queue manager service gives you control over the flow of messages through the queue by allowing you to set options based on your individual system's needs. For example, the queue manager can regulate SMTP32 threads so that the maximum is not exceeded. A daily report can be sent to a configurable address that details the servers performance in the following areas: the number of statistical filtering and phrase filtering matches, the number of viruses caught by IMail Anti-Virus, and the number of local and remote deliveries.
