I would output the headers the same way they are in the message, maybe an 
option to unfold lines.

How about LDIF-like syntax:

<tag>: <text>
<tag>: <text>
  continued line

So:

flags: \seen \draft $Label1
uid: 1234
hdr: Received: stuff
hdr: Received: more stuff
hdr: From: tss at iki.fi
  continued line of From:
body: line 1 (8bit probably encoded??)
  line 2
  line 3
<<really blank line separating items>>

I would agree with Nikita to not use this scheme, but something you can 
parse easily and put into a loop, say

doveadm search INBOX from me at example.com | while read uid trail; do
   doveadm fetch "$uid"
done
