m> is the client a MUA or an MTA?

It's MUA connections (MUA->MTA->target MTA)

and it's not bounce (queue ID is the same and no "message_queue_ID:
sender delivery status notification: bounce_queue_ID" line for this
message).

And one more question about postfix DSN.
Why in logs DSN's "from" is not "MAILER-DAEMON@bla-bla-bla"
(it's "from=<>" too) like "From" field in DSN message?

(Debian etch postfix 2.3.8-2+b1)
