Same here

+1. I added a new line to my fail2ban postfix jail to catch this event
(based on the succeeding smtpd log entry):
mdre-normal=...
^warning: Illegal address syntax from [^[]*\[<HOST>\] in MAIL
command:
symtom solving, is postconf -nf hard ?
i like to know if smtputf8 is enabled or not
is glibc support iconv, is idn supported on the host ?, it imho a build
error not a postfix error
other then that i just like to know more
since you ask:
# postconf -nf|grep utf
strict_smtputf8 = yes
Standard postfix 3.4.13 build on Debian (Ubuntu 20.04). My glibc is
Ubuntu GLIBC 2.31-0ubuntu9.3, I don't know how to test for its iconv
support. Never had such log message before this weekend; I assume the
cause was malign.
