Wietse,

Thank you for this pointer. My file "clientwhitelist" ends with

>>>>>
fmmailgate06.web.de OK
mail.gmx.de OK

  om-verisign.rgc3.net OK
<<<<<

(notice the leading blank in the last line). Could this be enough to
make Postfix interpret this as a continuation to the "mail.gmx.de OK"
line and turning this into "mail.gmx.de OK om-verisign.rgc3.net" which
would then cause the problem? Anyway, I have removed the leading blank.

Thank you very much for your help!

Carsten
