Outgoing SMTP Connection without basic authentication

Question

Hello together

I have installed Jira Service Management Data Center 5.4.1 LTS. I am now trying to set up an outgoing mail connection. On our SMTP server we do not have authentication enabled. So I don't have to enter a username and password. So I can just send mails to smtp.mycompany.com port 25.

When setting up in Jira, I have to select Password (basic authentication) for Authentication Method so that the Test Connection button becomes active at all. The user name and password are optional. That's why I don't enter them, because we don't need a user name and password either. Unfortunately I get the message

Unfortunately no connection was possible. Review the errors below and rectify:
AuthenticationFailedException: 535 5.7.0 authentication failed

How can I set up an SMTP connection without having to create a user for authentication?

Regards
Patrick

I sort of followed a hint found here: https://jira.atlassian.com/browse/JRASERVER-74326

I connected to the database and updated the config per SQL update. An ugly hack, but it worked for us.

select * from mailserver

-------+------+-------------+----------------+--------+-----------+----------+-------------+----------------------------------+--------------+------------------+--------------+---------------+---------+------------+------------+-----------+--------------

jira=# update mailserver set servername = '192.168.1.10' where id = 10000;

UPDATE 1

jira=# update mailserver set smtp_port = '25' where id = 10000;

UPDATE 1

jira=# update mailserver set mailusername = '' where id = 10000;

UPDATE 1

jira=# update mailserver set mailpassword = '' where id = 10000;
