Ergo, it isn't done :-) People do mail delivery via NFS all the time. They'll do so as long as NFS exists. Please don't delude yourself into thinking that you will stop them. > NFS for e-mail is evil and people who do it should be shot. I can agree with you, but again, the fact that we agree won't stop people from using NFS for this purpose. > POP and > IMAP are perfectly reasonable ways of collecting e-mail (and yes, I do > know what the subject of this discussion is/was).

The fact that you might be able to determine the correct locking method *now*, when the mail system is installed, is no guarantee for the future. In the future some other system administrator could take over, details be forgotten, the mail spool might be NFS mounted, etc. And suddenly people might start losing mail, because only one locking method was used that no longer worked reliably. I think Mark is trying to do his best to avoid losing mail, in the face of NFS and other problems. I certainly can't fault him for this, even if I don't always agree with his conclusions.
