André, are you quite sure you have it working?
In this thread someone from Open-Xchange stated that no, Dovecot doesn’t have SMTPUTF8 support implemented, and the same response was given by another Dovecot developer last September (it ‘is being considered’ was the answer then, see https://dovecot.org/pipermail/dovecot/2018-September/112887.html).
I am using LMTP to deliver mail to Dovecot from Postfix, and delivery fails with Postfix reporting: ‘SMTPUTF8 is required, but was not offered by host mail.my.org[private/dovecot-lmtp]’. I doubt that this can work without a change in Dovecot LMTP.
Anyway, I am also interested in SMTPUTF8 support, so +1 from me!
Hello David et al,
I have it working with my set up, and I confirm it is not easy.
If I limit the stack to OpenLDAP, Postfix and Dovecot to their simplest configuration, it is relatively easy, even with slightly outdated software in Debian Stretch. I think you are confusing acceptance of UTF8 in the localpart of the email address (which if I remember correctly worked in the 2.2 branch) with SMTPUTF8 support. As mentioned in the thread above Dovecot does not as yet support SMTPUTF8. Support for SMTPUTF8 would mean among other

John Hello John,
You are probably right.
I am not well aware of the low level details and the terminology.
I confess I am mostly interested in the proper reception of the emails with accentuated user names, which is already sometimes difficult to achieve.
Is there any link where I can learn the communication rules between Dovecot and Postfix and the SMTPUTF8 standard ?
Kind regards, André
André
Daniel Lange has posted some links to this topic from Postfix and earlier discussions on the mailing list.
Postfix has this SMTPUTF8 documentation:
http://www.postfix.org/SMTPUTF8_README.html
On that page you can also find links to the relevant standards including SMTPUTF8 standard.
