Thanks for the info.

I don't meet the last criteria: some users have direct file access via
pine and other mail readers.  There's also procmail, but I don't know
what locking method it uses.  Reading the pine sources closely, I think
it fakes fcntl() for NFS mailboxes.

I'm using dotlock_try which solves my immediate problem of allowing
users to delete Email under full quota.

The long term solution is to replace file access with kerberized IMAP
access, but that's much further down the road.
