If your company uses a Lotus Domino infrastructure for e-mail only, you can use a variety 3rd party Linux e-mail clients that support either the POP or IMAP protocols. Some Linux e-mail clients you might want to consider include Ximian Evolution, Mozilla Mail and KDE Kmail.
There are also many Instant Messaging (IM) client choices for Linux desktops such as GAIM, Kopete, Ayttm and Eb-Lite. These clients let you choose from a number of instant messaging protocols including MSN, Yahoo, AIM (TOC), IRC and Jabber. To my knowledge, none of these IM clients directly support Lotus' SameTime protocol.
