Dear all,
I was just confronted with the following bouncing message:
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])
So my question is: Is it possible to enable UTF-8 support for Cyrus
LMTP for email addresses and message header values and how?
Quoting Postfix SMTPUTF8 README
(http://www.postfix.org/SMTPUTF8_README.html):
/"Enabling Postfix SMTPUTF8 support//
//
//There is 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. "/
As a work-around I disabled UTF-8 support in postfix by adding:
'smtputf8_enable = no' in 'main.cf'
Cheers
Roland
