CPS (Coherent Printing System) is a Foomatic/GhostScript-based print spooling system for Linux which controls printers correctly even when the same physical printer is used in several different modes under different names (e.g., draft, colour, and greyscale on the same inkjet). All spooling is handled by the central daemon which allows network job submission to work without installing the print daemon, Foomatic, or GhostScript on the client machines. Samba printing is also catered for.
Coherent Mail Gateway is intended to be a very easy to set up MTA using SMTP and POP3. Greylisting is used on the SMTP daemon to reduce spam. In addition, quite a lot of checks on the validity of information from the SMTP client (such as claimed server name and sender) are carried out, and anyone caught telling lies is disconnected. Grey-, black-, and white-listing are supported, as well as (optionally) ClamAV and Spamhaus. The target market is users with static IP addresses. Others can use the system, but its value will be limited to outgoing email.
