qmail-newu - prepare address assignments for qmail-lspawn
qmail-newu reads the assignments in QMAILHOME/users/assign
and writes them into QMAILHOME/users/cdb in a binary format
suited for quick access by qmail-lspawn.
If there is a problem with users/assign, qmail-newu
complains and leaves users/cdb alone.
qmail-newu ensures that users/cdb is updated atomically, so
qmail-lspawn never has to wait for qmail-newu to finish.
However, qmail-newu makes no attempt to protect against two
simultaneous updates of users/cdb.
The binary users/cdb format is portable across machines.
