That should be quite ok, and harmless, however
something inside is then failing...
What happens when you do following test ?
$ $MAILBIN/router -i
z$ router '"email@example.com"@[184.108.40.206]'
Do note the quoting!
The result _should_ be:
(((local .... .... ....)))
... and thus the message would be attempted to be delivered to
local recipient address "firstname.lastname@example.org" -- which local user
does not exist, and it will thus bounce to its original MAIL FROM
I have a feeling that your router scripts are not in par with
the router program itself.
