» On Wednesday, Novell announced a partnership with China Standard Software Co. (CS2C) of Shanghai to help expand and promote Linux adoption in China. The two companies will compete against China's number-one Linux vendor, Red Flag, as they partner on services, marketing, and technology support issues to give Chinese organizations "enterprise-class Linux services and local and global support." News also came through Wednesday that Novell has lured Jeremy Allison, one of the core programmers behind Samba, from HP. Allison, who will start immediately at Novell, said the reason he made the switch was to benefit from Novell programmers' experience with file servers.

» There's a new sheriff in town on the Debian project. After four unsuccessful runs for the position of Debian Project Leader (DPL), Branden Robinson has been elected over five other candidates. His first challenge, as noted in an e-mail sent yesterday, will be to move Debian toward a regular release cycle and move the much-delayed "Sarge" closer to gold.

» 64-bit is rapidly becoming all the rage, and Terra Soft Solutions has latched on to the trend with the release of a 64-bit version of Yellow Dog Linux. The interim set of ISOs is available for immediate download as part of Yellow Dog Linux v4.0.90. The new version offers double-precision, support for 16 GB of RAM, a native runtime environment for both 32- and 64-bit code, a bi-arch (32/64) toolchain, Core 64-bit libraries, and an updated X.org, which corrects Aluminum Cinema display issues.

Tips of the Trade

The Linux/Unix world contains many mail servers, and most of them provide superior performance, features, and security. One that is rather different from the rest is PowerMail. PowerMail is a distributed, redundant system capable of receiving and delivering large volumes of mail quickly. It has a central user account database, which obviates the need for system accounts, and users' mailboxes can be located anywhere. You can even set up redundant mailboxes in different locations to add fault-tolerance.

PowerMail is very fast because there is no mail queue or message store — messages are routed directly into users' mailboxes. Bulk mails are delivered only once; copies are made and hard links created for the remaining recipients. Scaling up is easy, since mailboxes can be located anywhere — just add more storage.

Configuration is simplified because you don't have to mess with configuring domains. The mailbox name includes the domain, like "carla@mykewlserver.com." Adding a new user account means simply adding the user to the PowerMail account database. The database backend can be just about any database you like; MySQL is the default. It runs on Linux, Unix, FreeBSD, Mac OS X, and Windows.

PowerMail's limited feature set is its Achilles Heel. It cannot handle outgoing mail and does not support IMAP, or external mail handlers like procmail, Amavis, or Spamassassin, though these may be added in future releases. See PowerDNS.com to learn more.
