The Cyrus IMAP server is generally intended to be run on sealed systems, where normal users are not permitted to log in. The mailbox database is stored in parts of the filesystem that are private to Cyrus. All user access to mail is through the IMAP, POP3, or KPOP protocols. The private mailbox database design gives the server large advantages in efficiency, scalability, and administratability. Multiple concurrent read/write connections to the same mailbox are permitted. The server supports access control lists on mailboxes and storage quotas on mailbox hierarchies, multiple SASL mechanisms, and the Sieve mail filtering language.
OpenGroupware Coils is a Python port of the venerable OpenGroupware project. It is backward compatible and can be installed in parallel with legacy versions of OpenGroupware. It provides additional features including an AMQP-based service architecture and a BPML-based workflow engine. The workflow engine includes the ability to read and write a variety of file formats, operate on relational database services, and a variety of common actions required to automate various tasks. Groupware resources and workflow route, processes, and formats.can be managed via WebDAV. Groupware functionality can also be accessed via the zOGI XML-RPC API just as with legacy ZideStore servers.
Simply excellent. I can install openSUSE and immediatley get to work. Yast management interface is excellent and the package selection is robust and current. Hardware support best-of-breed. In-place upgrades have a very high success rate. Sound, suspend/resume, wireless, all work out-of-box.
This is a priceless [and free!] package. Watching network traffic flows in this excellent visualization is incredibly useful. Not network administrator should be without this tool.
