Addresses is a GNUstep address book that consists of a full-featured address book manager application, a source-code compatible replacement for Apple's AddressBook.framework (for accessing and manipulating address data programmatically), a framework of view/editor classes that make it easy to use Addresses from your own programs, and a number of tools. It is easy to use by both users and programmers and can store almost all imaginable data, including multiple phone numbers, emails, and addresses, photos, AIM/Jabber/ICQ/Yahoo IM details, and notes. It supports drag-and-drop and integrates well with GNUMail.

You can then retrieve email and attachments from the database by searching on Date, From, To, Subject, Mailbox, or Body text.
Scalable OGo (SOGo in short) is a groupware server built around the SOPE application server. Unlike OGo, it is focused on scalability instead of depth in functionality. The Web interface uses human-readable URLs and can be accessed according to REST Web service ideas. Notably, it requires no server side session at all. The server stores all internal data in the iCalendar format, and therefore has no data model inconsistencies with native clients. It easily connects using GroupDAV connectors.
