Mailserver Configuration doesn't work


The confluence mailserver configuration doesn't work with our exchange server.

In the field hostname i wrote: The port 25 is open.

And then when I click on "Send Test E-Mail" this errorcode

An error has occurred with sending the test email. If your mail server requires authentication, please ensure that TLS or SSL is enabled on your server for the specific mailbox. If your mail server allows anonymous connection, please remove the username and password from the configuration and try again.

com.atlassian.mail.MailException: javax.mail.AuthenticationFailedException: No authentication mechansims supported by both server and client


when I test it with the gmail-smtp server all works well.

I hope you can help me.

That means Confluence is trying some form of authentication that Exchange is not set up to accept.

First check what you have set up for Confluence, then ask your Exchange admins to enable your user to authenticate to the Exchange SMTP system.

Your Exchange admin must grant your Confluence server to send email.
