CDO is a wrapper for MAPI, and no, CDO doesn't have to be installed if you want to use direct MAPI calls. SendObject uses MAPI under the hood, but unfortunately, MAPI is a security sieve, which has resulted in all those not so friendly security patches on Outlook. We test for CDO because we don't use SendObject and we don't use direct MAPI to handle the email operations. Outlook can be installed without CDO in later versions but we have to support older OS setups and Office installations where in fact CDO *is* what is used, so we use Redemption and test for OLEMessaging to tell us there is a acceptable email client installed.

Charlotte, Are you sure that CDO is 100% needed for SendObject? I thought (just thought - I don't have any docs on this subject) that SendObject works when MAPI support is installed - but I don't know how to check is MAPI present or not.
