Hi Daniel,

Thanks for helping me on this. Here are the answers to your questions.

Yes this is all true.

I tried it using an external imap mail client (Thunderbird), roundcube
would be the next step in my opinion.

yes, authenticating as joe at example.org but setting an email address as
mail at myexample.org (virtual example).

yes I'm using port 587 (STARTTLS). Here are the relevant lines from
/var/log/maillog:

Sep  2 13:23:47 <host> postfix/submission/smtpd[17059]: connect from
<clienthost>[xx.xx.xx.xx]
Sep  2 13:23:48 <host> postfix/submission/smtpd[17059]: 6720AE0882:
client=<clienthost>[xx.xx.xx.xx], sasl_method=PLAIN,
sasl_username=joe at example.org
Sep  2 13:23:48 <host> postfix/submission/smtpd[17059]: 6720AE0882:
reject: DATA from <clienthost>[xx.xx.xx.xx]: 554 5.7.1 <DATA>: Data
command rejected: Could not find envelope sender user
mail at myexample.org; from=<mail at myexample.org>
to=<receiver at virtual-example.org> proto=ESMTP helo=<[xx.xx.xx.xx]>

The mails get accepted if I change "submission_data_restrictions = " to
an empty string in postfix' main.cf.

Many regards,
Sebastian
