My last reply to this thread, then.

The answer to your main question would be 'yes', since Dovecot's IMAP 
interface supports retrieving the entire email message including all its 
meta-data (aka headers or envelope).

The mbox from-line, not to be confused with the From: header, is simply 
not part of the email message but used only as a separator.
Heck, it need not even contain valid information, but only proper 
formatting to satisfy picky/"smart" MUA's. Usually, it conveniently does 
carry some useful information, but e.g. when the SMTP envelope-from is 
'<>' then the mbox from-line usually contains something like MAILER-DAEMON 
to stay within the formatting specification.

So, instead of blaming others of derailing a discussion and/or not simply 
answering a question, it might be an equally good idea to think twice 
about how you asked the question.

I'm actually happy that 'simple' questions are handled the way they are. 
Most people do not want an answer to the question they asked, but want a 
solution to their problem. Which they may have described in the question 
but often is left as an exercise for the reader. ;-)


But then again, I'm a technician, not a shrink, so my apologies for being 
so unfriendly...
