You could run courier or qmail with maildir however. I use a patched version of qmail (and I love it), your can read about my experiences here (please note, I haven't quite finished this document yet and it is still a little rough around the edges): (http://tabor.taborandtashell.net/serversetup/qmail.html). As for a web server, I don't know of any file locking problems, although for some specific implementations I would presume that they would pop up (ex: anything to do with a Berkley DB). So, in short the answer to your question is: depends. Note: I am not an expert unix system administrator, nor have I ever had a disk less server, I have however been monkeying with unix for about 8 years now.
