thanks for the answer, yes, but ai m searching for something which tells me, what the problem is. it’s tricky as the wireshark trace shows the e-mail is sent, but no response is given. normal e-mail using Linux sendmail works with no issue. SPF and DKIM is set on the respective domain as well. I am able to reproduce the issue on the rails console.

message = TestMailer.send\_test(“[ycxi@examle.com](mailto:ycxi@examle.com)”)  
Email::Sender.new(message, :test\_message).send

I am not a ruby expert at all, I will see if I can get some more verbose logging than a stack trace:

[5] pry(main)\> wtf?  
Exception: Net::ReadTimeout: Net::ReadTimeout
