dovecot - Mar 2007 - Wiki needs updating: Dovecot LDA + Dovecot Sieve + Exim

So as to make sure that Dovecot Sieve's vacation system works Exim has to be
forced to generate a "Reply-To:" header in the message (which it
doesn't do
by default). The current example for using the Dovecot LDA with Exim doesn't
do this.

Here is a replacement example for the local_delivery transport:-

local_delivery:
  driver = pipe
  command = /usr/local/libexec/dovecot/deliver -d $local_part
  message_prefix   message_suffix   log_output
  delivery_date_add
  envelope_to_add
  return_path_add
  headers_add = Reply-To: ${if def:header_reply-to:{$h_reply-to:}{$h_from:}}
  #group = mail
  #mode = 0660

Basically, if the Reply-To: header exists than it merely gets overwritten with 
itself. If it doesn't then the header is created and the contents of the
From
header is put into it.

If this is not done then the libsieve over restrictive rules (requiring 
a "Reply-To:" header even though the RFC doesn't require it) will
not allow
the vacation system to work.

The nice thing of Wiki's is that you can update pages YOURSELF. Just
register (if needed at all) and add/change what you want. Me think Timo can
spend his time better on patching the source.

Hmm. Really? Not in my tests and I don't see hardly anything related to
Reply-To in the code. It should send it to the address specified in
Return-Path.
