Have you defined MM3_LMTP_PORT and is it the same value as the lmtp_port: setting in the [mta] section of mailman.cfg - default 8024?
And is Mailman core and particularly its lmtp runner running and is it listening on the relevant port?
Is there more information about "all hosts for 'listen.td3.eu' have been failing for a long time" in exim's logs?

Hello Mark,
thank you four your fast response, yes I use the default port 8024

What do you have in mailman.cfg for the [mta] section? I have a very similar setup to you and just have the following:
[mta] incoming: mailman.mta.exim4.LMTP configuration: python:mailman.config.exim4
Hope this helps. Andrew.

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.

Please report back if this is the solution. If it is, we'll update the docs.

Hello Mark, Andrew,
thank you for your hints, the hosts_override gives me the way to solve my problem.
It was a problem of DNS + resolv.conf,
- inside resolv.conf there is a domain search defined, - search example.com -
- Inside the Domain example.com there exists a record "* in a 85.25.8.21", so the question localhost resolvs to localhost.example.com ... 85.25.8.21
After I added the localhost in a 127.0.0.1 into the domain, the exim transport delivers correctly.
greetings Thomas
