That's correct.

Note that what I wrote below applies only to the exact log entry
"Message discarded, msgid: <...>". It seems that's the one you've seen,
but there can be other messages such as "No command, message discarded,
msgid: <...>" which is logged for messages sent to the -request address
with no command or to -confirm with incorrect format.
