[Members] Malevolent listener on pubsub ml?

[jehan at zemarmot.net]

Hi,

each of my messages on the pubsub ml immediately gets, as a response 
(to me directly, not to the list), an email in German from 
postmaster at szameit-steuerberater.de. I did not try to translate what it 
says (but basically, looks like a typical error email, even though the 
email passed through well).

Am I the only one it happens? Wouldn't it be some bot registered on 
the mailing list and answering every email with this fake error? Could 
some admin look at this?
Thanks.

Jehan
