Hi

I have problem with SMTPUTF8 support for incoming mail.
I have Postfix 3.3.0 version.
I add etc/postfix/main.cf
smtputf8_enable = yes
smtputf8_autodetect_classes = sendmail, verify

restart postfix service (sudo /etc/init.d/postfix restart)

No change.
I have this error message - SMTPUTF8 is required, but was not offered by host 127.0.0.1[127.0.0.1])

Any suggestions  ?

How did you reproduce this error?
Please show us output of command "postconf -m".

Re: Postfix SMTPUTF8 support

Hi, the actual problem is that the SMTPUTF8 is disabled in amavisd but enabled in postfix.
postfix/amavis/smtp[1052240]: 4DX5yB0kc5zJpm2: to=<ko@ne.com>, relay=127.0.0.1[127.0.0.1]:10026, delay=0.38, delays=0.36/0/0.02/0, dsn=5.6.7, status=bounced (SMTPUTF8 is required, but was not offered by host 127.0.0.1[127.0.0.1])
