It's not clear to me from the log what is happening. It all happens within a fraction of a second, so there don't seem to be any time outs involved. It seems the first two entries are the delivery of the message from th@drillich.com to exim for seebruecke@listen.td3.eu.
I'm guessing here because I don't know that much about exim, but it looks like exim is trying to connect to listen.td3.eu rather than localhost to deliver the message and most likely, port 8024 is not open to the outside which is correct.
I think you need to add
hosts_override = true
to your transport definition to tell exim to use hosts = localhost
rather than the host part of the email address.
