Without looking at the actual log files on both the squeak list server 
and ba-stuttgart.de's receiving mail server, it's difficult to tell what 
went wrong.
Since nobody else seems to be having this problem (at least nobody 
yelled about it), I am fairly sure that the problem is in the setup 
between these two machines.
One possibility is that ba-stuttgart.de is trying to do greylisting by 
answering with SMTP temporary error codes, but delivers the message to 
the recipient anyway.
In that case the squeak list server is perfectly right in re-sending the 
message (since it got a temporary error which tells it to do so).

However, as I said, without looking at the logs it's impossible to tell.

Cheers,
Hans-Martin
