Does Thunderbird connect to the your external or internal IP address?

213.193.81.54 is not an open relay. I've got no idea where it got that idea from.
And I'm no even using 213.193.81.54 to send my e-mails, I'm using thunderbird which directly connects to my smtp server. 213.193.81.54 is my external ip address (and also the smtp server of the company I'm working at right now, but it's neither an open relay, nor is used for those transactions in any way).
It also doesn't give me that openrelay message for the mail I'm sending right now. I guess it must be related to the " No SMTP response to data-dot " error.

Is the IP address 213.193.81.54 the IP of your email server? If indeed you have an Open Relay, you certainly have a big configuration issue.
