In a case like this, could nmh still get new mail by using POP or some
other method that lets the mail server handle locking? Or, when a user
tries to run inc, nmh could:
- print a warning and have a -force option
- default to less-than-perfect locking
- ...?
I'm not an expert on mail delivery, so I don't know how many disasters
are likely if locking isn't atomic. But the lack of links has kept nmh
off of a number of filesystems (and OSes) for a long time. If there's a
"good enough" solution with clear warnings about the chance of a
problem, it would let users make their own decisions.
(I use nmh mostly for archiving, searching, and replying to stored
messages. The only time I run inc these days is when I'm fetching the
last week's worth of mail from my mail host's inbox, which I normally
access via IMAP.)
