RE: [ext] Re: User Docker image apache/james:demo-3.6.0: SMTP problem

Dear Benoit,

thank you for your fast answer. I am not sure whether this applies to my issue, since I used Thunderbird authenticating the user with a password (although unencrypted). If I understand correctly, the issue is about unauthenticated users. Is that correct?

Regards and thanks for your time

Felix

Hello,

Please refer to https://issues.apache.org/jira/browse/JAMES-3525

TL;DR Your MAIL FROM is the one of a local user. If we accept the email without authentication, anybody could trivially still your identity, which would be a major security flow.

Regards,

Benoit

After adding, the IMAP connection to check for new e-mails works as well (although ofc, there are none). However, I cannot send e-mails by SMTP to one of the user users or the same user. The error I see in Mozilla is "Authentication required". I do not see entries in /log/james.log which I can refer to the SMTP topic.
