Thanks for the replies. I have taken a look into the code. The mlookup
thing is indeed very simple and already working. The cmd_append() part
is a bit tricky tho, as the LMTPD does not have any imap connection to
the backend as far as I see. I guess LMTP will be the wrong way to
transport the mail to the right backend server.
As I am completly new to the cyrus code, does anybody has any hints
what would be a good start to get this done ?
