I have been using a macro that I got from the word.mvps.org website to Mail
Merge to E-mail with Attachments and it's working great.  I am using Word
2002 and I would like to set the email "From" field to my boss's name.  I
need to send out several hundred email messages and I would like to send them
on his behalf from my computer.  My boss has given me delegation rights to
send on his behalf but no matter what I do when I run the macro the email
messages are from me.  Can anyone help with the vba code to add this to the
macro script?  I think that's the only way that I'll be able to get this to
work.
Thank you...

Following is the macro script:
