* Create and write the file as the recipient, so that file quota work.
* Create any missing directories on the fly. The file name is chosen
* according to ftp://koobera.math.uic.edu/www/proto/maildir.html:
*
* "A unique name has three pieces, separated by dots. On the left is the
* result of time(). On the right is the result of gethostname(). In the
* middle is something that doesn't repeat within one second on a single
* host. I fork a new process for each delivery, so I just use the
* process ID. If you're delivering several messages from one process,
* use starttime.pid_count.host, where starttime is the time that your
* process started, and count is the number of messages you've
* delivered."
*
* Well, that stopped working on fast machines, and on operating systems
* that randomize process ID values. When creating a file in tmp/ we use
* the process ID because it still is an exclusive resource. When moving
* the file to new/ we use the device number and inode number. I do not
* care if this breaks on a remote AFS file system, because people should
* know better.

* A unique name has three pieces, separated by dots. On the left is the
* result of time() or the second counter from gettimeofday(). On the
* right is the result of gethostname(). (To deal with invalid host
* names, replace / with \057 and : with \072.) In the middle is a
* delivery identifier, discussed below.
*
* [...]
*
* Modern delivery identifiers are created by concatenating enough of the
* following strings to guarantee uniqueness:
*
* [...]
*
* In, where n is (in hexadecimal) the UNIX inode number of this file.
* Unfortunately, inode numbers aren't always available through NFS.
*
* Vn, where n is (in hexadecimal) the UNIX device number of this file.
* Unfortunately, device numbers aren't always available through NFS.
* (Device numbers are also not helpful with the standard UNIX
* filesystem: a maildir has to be within a single UNIX device for link()
* and rename() to work.)
*
* Mn, where n is (in decimal) the microsecond counter from the same
* gettimeofday() used for the left part of the unique name.
*
* Pn, where n is (in decimal) the process ID.
