Thanks for this info, Andreas. Nevertheless I'm a bit surprised:

- majority of messages get signed anyway, leaving only 0.25% messages not signed
- I've got another server, same exact settings, but running opendkim-2.9.2_6: no errors at all

I'll change permissions and let you know if it fixes my problem!

While I"m here: during my testings to find out what was wrong, I've used truss on the running opendkim process, and I was quite surprised to discover it stats /etc/nsswitch at a fast rate (more that 100 times per seconds). Is that expected?
