I've also confirmed Solaris client works OK; /mnt is the NetApp, the client is Solaris: > ./testnfs /mnt/home/cshenton/SOLNFS/ Transferred 200 out of 200 files > uname -a SunOS thing 5.9 Generic_112233-08 sun4u sparc SUNW,Ultra-60 > So this is starting to look like a FreeBSD issue Grumble...

I will submit a FreeBSD PR, although now we have the workaround it's not such a problem. Cheers, Brian.

I've just been able to test another platform: Solaris-2.8 client with a NetApp server. In this case I get 200/200 transferred. In fact I get 2000/2000 if I make the test that big as well. So this is starting to look like a FreeBSD issue; would be interesting to see if someone could try it with Linux client and/or NFS server. Cheers, Brian.

I just installed the current dev build of courier-imap though and it successfully works around the problem - i.e. on the first POP3 connection absolutely all mail is available. Cheers, Brian.
