Sent to Mail Recipient gone - get it back

After upgrading to Office 2007 from Office 2003 SP2 on XP Pro SP2, I lost the 'mail recipient' option when right click and file and going to 'Send To'.

I was able to restore it by running the command (Start>Run) regsvr32 sendmail.dll. Now when I right click something, like a .jpg, and go to Send To, Mail Recipient is an option.

I got the instructions for this procedure on Ramesh's site
