Have you tried using Internet search engines with Code: Diagnostic-Code: X-Postfix; unknown user: Maybe add Code: site: howtoforge.com
Tried your suggestion, thank you! Maybe in my case is because there was somebody tried to sent an email to: =?utf-8?q?$1086=20=d1=83=d0=ba=d0=b0=d0=b6=d0=b8=d1=82=d0=b5=20?= in which there was no address like that in my server. i try to sent an email to the valid address, and there was no error at all. so, is this a normal case? or is there anything that i could improve?

This is the normal case, a mailserver must reject email for non-existing addresses and this will be logged in the mail.log file.
check wether you have http://www.postfix.org/SMTPUTF8_README.html#enabling enabled. might cause issues from time to time if, like docs say, infrastructure doesn't support it 100%
Hi i didn't see : "smtputf8_enable = yes" in my main.cf which mean SMTPUTF8 wasn't enabled, right? i haven't modify anything on SMTP intaller since i only following tutorial provided by ISPConfig
have you tried it yet? default might be Code: smtputf8_enable = ${{$compatibility_level} < {1} ? {no} : {yes}} so it depends.
I tried, but no luck so i try another approach, since the pattern was always same, so i create a filter on mail content then discard those kind of email. Thank you for the support.
