User manual APPLE MAIL SERVICES DATASHEET

[. . . ] With support for existing SendMail infrastructures and scripts, in-place migration to the new mail server is easy. Mail services in Mac OS X Server are based entirely on open standards, providing compatibility with your existing network infrastructure, as well as with email clients on Mac, Windows, and Linux platforms. And because there are no per-user licensing fees, Mac OS X Server can scale to support hundreds of thousands of mail accounts-- without draining your software licensing budget. Robust Postfix and Cyrus mail services Mac OS X Server uses Postfix, a highly secure, high-performance mail server, as its SMTP mail transfer agent and Cyrus for scalable, enterprise-class IMAP and POP mail services. [. . . ] You can choose from Kerberos, CRAM-MD5, and APOP, depending on the needs of your organization. Fully integrated into Open Directory, Kerberos provides the added benefit of single sign-on--for both Mac and Windows users--to all "Kerberized" services across the network. Webmail using SquirrelMail Webmail allows you to extend your mail services, enabling users to access their email from any standards-based browser. Apple's webmail is based on SquirrelMail, an open source webmail package written in PHP 4, and provides all the functionality you would want from an email client--including support for MIME, address books, and folders for organizing stored messages. Since PHP is fully integrated with the Apache web server, webmail pages render in pure HTML 4. 0--with no JavaScript required--for maximum compatibility across browsers. SquirrelMail is very easy to configure and works with any IMAP server. Technology Brief Mac OS X: Mail Services 3 Setting Up Mail Services The Server Admin application in Mac OS X Server provides all the tools for configuring and delivering secure, authenticated mail services to users across your organization. Enabling services Server Admin features an easy-to-use interface for setting up SMTP, POP, and IMAP services and managing mail settings. Simply select the protocols you want to enable and click the Start Service button. You can also define general postmaster settings, including the copying of undeliverable messages to a specified email address and archiving of incoming and outgoing messages. Directory-based account management Workgroup Manager integrates seamlessly with Mac OS X Server mail services for simplified directory-based management of mail settings and policies. It allows you to create IMAP/POP accounts, enable mail services, set individual quotas, specify mail storage location, and define authentication methods. User account information is stored in Open Directory, Apple's standards-based directory services architecture that works with any LDAP server. Advanced settings for mail services Server Admin also makes it easy to configure more advanced mail server options. For example, you can define multiple mail server host names, or virtual domains, for the local server, and you can choose authentication methods and security settings for each mail protocol. You can also designate any storage volume connected to the server as the default location for storing mail messages. Organizations handling high volumes of email or requiring data protection may choose to use a high-availability RAID solution, such as Xserve RAID, for mail storage. Technology Brief Mac OS X: Mail Services 4 Protection Against Junk Mail and Viruses To protect your organization from unwanted mail and destructive viruses, Mac OS X Server v10. 4 integrates two popular open source projects: SpamAssassin for adaptive junk mail filtering and ClamAV for virus detection and quarantine. With SpamAssassin, Mac OS X Server analyzes the text of each mail message. Using a wide variety of local and network tests, it assigns a probability rating that the mail is spam. If the probability is high, it classifies the mail as potential junk mail and allows the user to decide how to handle it. The SpamAssassin junk mail filter is adaptive, which means you can train it to recognize which marginal mail messages are spam and which are not. Training can be automatic: SpamAssassin can analyze the content of user inboxes every night and adapt its filters accordingly. [. . . ] This extensive information can help you create usage reports and plan allocation of server resources for your organization. And for UNIX-savvy administrators who prefer a scriptable, command-line environment, all Server Admin capabilities are accessible from the Terminal application. Apple Server Solutions Mail services are among the powerful workgroup and Internet solutions built into Apple's UNIX-based Mac OS X Server operating system. Combining the latest open source technologies with Mac ease of use, Mac OS X Server unleashes the power of Xserve G5, Apple's rack-optimized server hardware. [. . . ]
