I frequently compose e-mails as subtrees of my org files. I'd like to be able to e-mail the contents of these subtrees, maybe by first viewing the subtree in an indirect buffer. 

My org files look like this:

* e-mails
  ** note to person about blah
     To: person@blah.com
     Subject: ADD people 7 times more likely to be creative
     --text follows this line--
     
     Dear Person,
     
     Blah blah blah. 
     
     Best,
     Peter

I can open the subtree in an indirect buffer, but I can't e-mail the contents as they appear because I get "Invalid header line." 

If I delete the org-header, I can successfully send the e-mail. But then I need to undelete the header afterward. 

How can I send the contents of a subtree as an e-mail without first having to delete the header? 

Thanks,
Peter
