problems on SuSE Linux 7.2

Hallo all,

I use procmail version 3.13.1 on SuSE Linux 7.0 without any problems.
Since I configurated a mailserver (incl. procmail version 3.15.1) on SuSE Linux 
7.2 procmail is not working. All local mails will delivered only by fetchmail 
... "is user xyz".

Is there any important changing between thís versions or the SuSE distributions 
?
How can I maake procmail working ?

Thanks

Regard

Willi
