Hmmm... I replied to this at the weekend but the message doesn't seem to have 
reached the list.  Must have chosen the wrong reply option :(

Delivered-To: is set by qmail when a message is delivered.  Because it is 
qmail specific it is not reliable.  In any case it is non standard and should 
start with an X-.  I don't know if there is a formal definition of its syntax.

Original-Recipient: is part of the Multipart/Report content, specifically the 
machine readable message/delivery-status part.  It is present only if the SMTP 
DSN extension is used and then only if the ORCPT parameter to the RCPT TO 
command is present.  It is *not* a message header, it is structured data in 
the body of a message/delivery-status part.

Since both are nonstandard message headers they are unreliable and 
undocumented and assumptions about their misuse by various MTAs should not be 
coded into balsa.

In any case, the identity per mailbox patch I submitted a while ago should 
solve the problem, details are in the archive.  In short edit ~/.gnome/balsa 
and add a line "Identity=identity-name" to the section for the desired 
mailbox.  "identity-name" corresponds to one of the identities in the 
Identities dialogue. (I really will code some UI for this in the near future!)

Alternatively, it might be useful to be able to filter on the content of 
arbitrarily named headers in the filters dialogue in addition to the 
From/To/Cc/Subject or All options.
