Personally? I've found Mandrake 10 with the KDE interface to be the easiest to install and operate for beginning Linux users.
Installation isn't a bear like it can be with Debian and others, and the standard windows user is usually able to navigate about the box's GUI with little problem.
If you're looking to setup a server however, Mandrake probally isn't the best solution as it's more designed for workstation/home use. It is possible, just not recommended. Use Debian or Redhat should you with to start a server.
There is another option however should you not want to install anything onto your HDD. The Mandrake 'Move' disk and a version of Linux called 'Phlak' both boot off of CD (And aye, these aren't the only ones, these are just examples.) making it nice and convienent for those wanting to dabble a bit before deciding to become serrious Linux/Unix users. The Mandrake 'Move' disk specifically makes mention of being able to save to devices such as usb pen drives though I believe this is pretty much standard anymore on most distributions and their various forms unless specifically removed.
I'd recomend trying to learn the command line first - especially the Man files. Pretty much everything one needs to know can be found in those, and if not, a simple google search usually answers most questions. (ie: 'sendmail howto' in the google search box.)
Again, these are just opinions based on personal expirence.
