Answers.Text: This was my guess too. But why does the same configuration work on smtper.net? As long as the sender e-mail is in our domain everything works fine.

  (Asked by: username_0 on 2019-05-27)
  
  I try to send e-mails via SMTP without authentification and I'm getting the following error:
  
  > There was an error testing your email settings.
  
  I checked my setup on <https://www.smtper.net/>. No problems!
  
  I read through the [troubleshooting-email-errors](https://craftcms.com/guides/troubleshooting-email-errors) page but still found no solution for my problem.
  
  Why can't I find a log under *craft/storage/runtime/logs/craft.log*. This file does not exist on my system. There is only *craft/storage/logs/web.log*.
  
  When I use another SMTP server (with auth) everything works as expected. Any ideas on how to find out what's going on here?
