Correct. The "dest.flush()" method creates a temporary file, copies the entire modified mailbox into it, removed the original file, and renames the temp file into place. The Postfix MDA, like most MDAs, just opens the existing file and appends the new data to it. >Has anyone seen this problem before, and/or do I need to anything more >than the following for the locking to work correctly:- It's not the locking. It's the flush mechanism. The mbox class doesn't know that the ONLY thing you did was an append. You might have modified other messages in the middle. If you want to do an append, you'll need to write your own subclass of mbox. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
