Even if you replace the python mbox code with something that uses fcntl.flock() to protect against concurrent updating, you should also understand that NFS does *not* provide full Unix filesystem semantics. In particular, Unix flock(2) (which Python's fcntl.flock() wraps) doesn't work over NFS.
That's why if you want to access mail over NFS, you should use maildir, rather than mbox, no matter what your programming language. -- Chris Jewell chr...@puffin.com PO Box 1396 Gualala CA USA 95445-1396 -- http://mail.python.org/mailman/listinfo/python-list
