Dovecot lmtp support for SMTPUTF8

[Igor Colombi]

Hello,

I'm using dovecot lmtp with Postfix.

I'm enabling SMTPUTF8 (EAI), but when Postfix (v 3.1.2) tries to deliver
the message to dovecot-lmtp it receive this error:

status=bounced (SMTPUTF8 is required, but was not offered by host
dlvmx.espsrv.net[private/dovecot-lmtp]

I'm not sure if Dovecot lda and lmpt support EAI and how can I enable it.
I've just found and old thread:

Thanks for your help.
