It's a side-effect of pipelining. If a client connects, and finds that
it can do pipelining, it will send the MAIL FROM, RCPT TO and DATA
commands immediately, without waiting for a response to each command, as
allowed by the ESMTP PIPELINING extension. However, if courier rejects
all the recipients, for example, then the DATA command is invalid, and
so courier will generate the "502 ESMTP command error" message. Nothing
to be worried about.
