The above logging is from the system that is sending mail into
Postfix.
To find out what commands the client sends you need to turn on
logging (debug_peer_list=192.168.1.1 or whatever).
I am pretty sure that your software does not correctly quote special
characters by the rules of RFC 821/2821/5321.
Postfix will not receive mail from clients that don't implement
basic SMTP syntax. This will not be changed.
