regression with lmtp_hdr_delivery_address in 2.3

[dovecot-ffe7 at ryanc.org]

Hi,

In my LMTP config, I have

lmtp_hdr_delivery_address = none.

Under 2.2, Received headers looked like this:

Received: from smtp.example.com
     by lmtp.example.com with LMTP id +IVdKS81cFwWagAAGhmRSA
     ; Fri, 22 Feb 2019 17:45:19 +0000

After the update to 2.3, they look like this:

Received: from smtp.example.com
     by lmtp.example.com with LMTP
     id MJbKAMFEclyKCQAAGhmRSA
     (envelope-from <yyy at example.net>)
     for <xxx at example.com>; Sun, 24 Feb 2019 07:16:17 +0000

In both cases I *do not* have a "Delivered-To" header

I do see a check for rcpt_to == NULL in the 
smtp_server_transaction_write_trace_record function, but it looks like 
the lmtp_local_add_headers function does not update the transaction, so 
it doesn't get pulled in. Also, the LMTP settings struct isn't exposed 
in that function currently, and I'm not sure how to add it.

In 2.2, both the "Delivered-To" and "Received" headers were handled by 
client_get_added_headers.

Please CC me in replies, as I am not subscribed to the list.

Thanks,
