The mailing list for listmasters using Sympa

[Claus Atzenbeck <address@concealed>]

When I write a mail to Sympa (e.g. the help command), I get back the
following message from postfix:

*****
    [ Part 2: "Delivery error report" ]

Reporting-MTA: dns; thor.germania.lan
Arrival-Date: Sat, 26 May 2001 22:06:32 +0200 (CEST)

Status: 5.0.0
Diagnostic-Code: X-Postfix; Command died with status 1:

In the log entry I can find many of those lines:

Please, could I get some help what is going wrong?

Thanks a lot for any hint!
