Solution found; traced qmail-local.c and determined failure encountered
in maildir_child() during a call to link(). Rummaging around AFS FAQ in
chapter on differences between AFS and Unix FS, it says that hard links
across directories are not supported by AFS because AFS ACLs protect
directories and not files, and allowing hard links to cross directories
would circumvent the ACL.
I changed the link() in qmail-local.c to rename() and my mail delivery
now works. Anyone want to put in some input as to whether a rename() would
fail in some cases where a link() might not?
