Re: [exim] how to change a recipient in a transport?

Hello,

maybe I should explain what I need it for: In my current setup exim is
delivering directly to a Maildir. If a message is found to be junk and
the user has configured to move the message to the junk-folder in this
case, exim is delivering it to the junk-folder:

address_directory:
   driver = appendfile
   delivery_date_add
   envelope_to_add
   return_path_add
   maildir_format
   directory = 
${lookup{$local_part@$domain}lsearch*@{/etc/mail/maildirs.txt}}/${if \
                 and { \

{eq{${lookup{$local_part@$domain}lsearch*@{/etc/mail/antispam.txt}}}{junk-folder}} 
\
                        {eq{$spam_score_int}{10}} \
                    } {.Junk/}{}}
   quota = ${lookup{$local_part@$domain}lsearch*@{/etc/mail/quotas.txt}}
   create_directory = false
   user = nobody
   group = nobody

Now I'm migrating to cyrus where messages are delivered via the
smtp-transport using lmtp. To deliver a message into the junk-folder, I
need to rewrite a recipient address like test@??? to test/Junk@???.

How can I do this?
