Introduction

MDaemon Technologies' MDaemon Email Server is a standards-based SMTP/POP3/IMAP mail server that supports Windows 7, Server 2008 R2, or newer and offers a full range of mail server functionality. MDaemon is designed to manage the email needs of any number of individual users and comes complete with a powerful set of integrated tools for managing mail accounts and message formats. MDaemon offers a scalable SMTP, POP3, and IMAP4 mail server complete with LDAP and Active Directory support, an integrated browser-based email client, content filtering, spam filters, extensive security features, and more.

### MDaemon Features

MDaemon is equipped with many features besides SMTP, POP3, and IMAP4 email processing. The following is a list of just some of those features.

•Complete support for virus scanning and protection is available as an add-on to your MDaemon or MDaemon Private Cloud license. This provides access to real-time Outbreak Protection, and MDaemon AntiVirus. Messages can then be scanned for viruses and cleaned or deleted automatically before ever reaching the intended recipients. Further, you can configure MDaemon to send a message to the administrator, sender, and recipient of the infected message notifying them of the virus.

•MDaemon features a complete suite of Mailing List or email group management functions allowing for the formation of an unlimited number of distinct distribution lists that can contain local and/or remote members. Lists can be set to allow or refuse subscription requests, be public or private, post replies to either the list or the originator of the message, be sent in digest format, and be configured using numerous other features.

•An integrated component of MDaemon is Webmail. This feature makes it possible for your users to access their email using their favorite web browser rather than from a workstation dependent email client. This tool is perfect for mobile staff and users who do not have a dedicated machine from which to access their email.

•MDaemon Webmail is equipped with a complete suite of email client features. You can: send and receive email, spell check messages, manage your email in multiple personal folders, display the interface in any of 18 languages, schedule meetings and appointments and share calendars and tasks with other users, manage your MDaemon account settings (when used in conjunction with Remote Administration), manage contacts, and more. Webmail is also equipped with MDaemon Instant Messenger (MDIM), a small utility that can be downloaded and installed on a user's local computer. This provides easy access to your email and folders and checks for new messages without having to open your web browser. It also includes a complete Instant Messaging system that can be used to quickly "chat" with other MDaemon users who are also using MDIM or another XMPP client.

•MDaemon is equipped with many features designed to help you make your email system secure. The Spam Filter and DNS Block Lists features will help you put an end to most "spam" email messages that "spammers" try to route through or to your domain. IP and Host Screening and the Address Block Lists provide the capability to screen and prevent certain addresses and domains from connecting to or sending mail through your system. They also make it possible to connect to specific IP addresses while screening all others.

•Equipped with support for Lightweight Directory Access Protocol (LDAP), MDaemon can keep your LDAP server up to date on all of its user accounts. This makes it possible for you to keep an LDAP address book up to date so that users with email clients that support LDAP can access it. You can also choose to use Active Directory or your LDAP server as the MDaemon account database instead of an ODBC compliant database or the local USERLIST.DAT system. Thus, you can configure multiple MDaemon's at different locations to share the same account database.

•MDaemon's extensive parsing features make it possible to provide email for an entire LAN with as little as a single dial-up ISP POP3 mailbox. This makes it possible to provide email to an entire network for a fraction of the normally associated cost.

•Address Aliases provides the ability to route email messages addressed to "fictitious" mailboxes to a valid account or mailing list. This makes it possible for individual accounts and lists to have multiple email addresses at one or more domains.

•The Domain Gateways feature provides the option of setting up separate domains for various departments or groups that may be local to your network or located somewhere else on the Internet. Using this feature, all mail addressed to a domain for which MDaemon is acting as a gateway will be placed in that domain's mailbox by MDaemon. It can then be collected by that domain's MDaemon server or email client and distributed to the domain's users. This feature can also be used to enable MDaemon to act as a backup mail server for other domains.

•Integrated web-based remote administration. MDaemon's Remote Administration component is integrated with MDaemon and Webmail and enables your users to review and edit their account settings via their web-browser. You can designate which settings that your users may edit, and assign access permissions on a per account basis. Remote Administration can also be used by the Administrator (and whomever else you wish to allow) to review or edit any of MDaemon's settings and any other files that you wish to make available to the Remote Administration system for reviewing.

•An internal message transport system known as RAW mail provides a simple method for placing messages into the mail stream and greatly simplifies custom mail software development. Using RAW, a complete mail system can be devised using a simple text editor and a couple of batch files.

•A highly versatile Content Filtering system makes it possible for you to customize server behavior based on the content of incoming and outgoing email messages. You can insert and delete message headers, add footers to messages, remove attachments, route copies to other users, cause an instant message to be sent to someone, run other programs, and more.

### MDaemon Private Cloud

MDaemon Private Cloud (MDPC) is a special edition of the MDaemon Email Server that was developed specifically for Managed Service Providers (MSPs) who wish to use MDaemon software to provide hosted email services to their customers. Unlike MDaemon, which is sold for on-premise use, MDPC was built on a new licensing and code foundation specifically designed for use in a hosted environment. MDaemon Private Cloud includes all MDaemon features and the following additional features:

•New licensing and billing (per-user/per-month)

•Outlook support

•Improved multi-domain control

•Per-domain branding (white label)

•Per-domain reporting

•Non-billable user test accounts (counts will not be included in total billing counts)

•Outbreak Protection, MDaemon Antivirus, and the ClamAV antivirus engine (optional with additional cost)

•ActiveSync for MDaemon (optional with additional cost)
