I was just confronted with the following bouncing message:<br /><br />
2021-11-04T11:34:34.498941+01:00 its42 postfix/lmtp[20495]:
6AE063099E9B: to=<server@localhost>,
relay=host.domain.net[/var/lib/imap/socket/lmtp], delay=0.07,
delays=0.04/0.01/0.02/0, dsn=5.6.7, status=bounced (SMTPUTF8 is
required, but was not offered by host
host.domain.net[/var/lib/imap/socket/lmtp])<br /><br />
So my question is: Is it possible to enable UTF-8 support for
Cyrus LMTP for email addresses and message header values and how?<br /><br />
Quoting Postfix SMTPUTF8 README (<a class="moz-txt-link-freetext" \
href="http://www.postfix.org/SMTPUTF8_README.html" \
moz-do-not-send="true">http://www.postfix.org/SMTPUTF8_README.html</a>):<br /><br \

more to SMTPUTF8 than just Postfix itself. The rest of your email infrastructure \
also needs to be able to handle UTF-8 email addresses and message header values. \
This includes SMTPUTF8 protocol support in SMTP-based content filters
(Amavisd), LMTP servers (Dovecot), and down-stream SMTP servers.
"</i><br /><br />
As a work-around I disabled UTF-8 support in postfix by adding:
'smtputf8_enable = no' in 'main.cf'<br /><br />
Cheers<br />
