the server and the client are on the same layer2 network and there is no hard- or software or anything else installed on the server what prevents traffic between them; i just figured out that it has to do with the nfs portion; while incoming mails have no problems and are delivered correct into the maildir on the nfs, it does not work when the client want to connect to the maildir; when i copy content from nfs-storage to the local harddisk it works;
Read these below, and post back if that doesn't help. Please remember to reply to the list next time, not to individuals. I'm not an NFS guru, and those who are didn't see your reply.
