3 This is the qmail home directory. It must be a local directory, not
4 shared among machines. This is where qmail queues all mail messages.
6 The queue (except for bounce message contents) is crashproof, if the
7 filesystem guarantees that single-byte writes are atomic and that
8 directory operations are synchronous. These guarantees are provided by
9 fixed-block filesystems such as UFS and by journaling filesystems. Under
10 Linux, make sure that all mail-handling filesystems are mounted with
~mdw / qmail / blob
