I can't send test mails – why?? :(

[Anonymous]

Hello,
I can’t send a test mail any more (if I want to test a new Newsletter I don’t get an email, too) – a week ago it was working and I thought I did not Change anything!?

If I enter my Mailadress under “Settings”–>”Diagnostics”–>”Tests” it is working:
Mail send with wordpress and with Newsletter: SUCCESS

If I go to “SMTP Settings” and send a test mail there is an error:

),
)

You can see my SMTP Settings in the Picture.

How can I fix that? I would like to send the next Newsletter on monday again!
Thanks for Your Help!!

The smtp setting is empty and not active, the test of course will fails without an host and other parameters. If tests are working (success) from the status panel, it is ok. If the email is not actually delievered, is a problem of the server you should report to the system administrator.
