Hello Markus,
Thank you for pointing me to the problem. It works after removing the
wildcard rule.
For some reason I did not consider the postfix config to be the culprit
at all, we also have the same rule file on our main smtp server. But
that one of course has additional config for configuring the users valid
sender addresses from ldap which is not present on this local postfix.
All understandable now.
Many thanks,
Thomas

If you have turned on postfix' canonical mapping with the above
configuration, then postfix will rewrite (in header and envelope)
<everything>@ida.ing.tu-bs.de to sysgr...@ida.ing.tu-bs.de.
To me, this seems to explain your observation just fine.
