NAME
mdir – mail directory format
SYNOPSIS
The
mdir
format is used by Upas as a replacement
for tradition mailbox format. An
mdir
mailbox is a directory containing any
number of messages stored one message
per file. Individual messages are stored
in the same format they would be in a
traditional mailbox; each message is a
valid mailbox with a single message.
The message files are named with the
UNIX seconds corresponding to the date
on the
From
line, a “.” separator and a two digit
sequence starting with
00.
One
mdir
may contain other
mdirs
but (currently) this relationship is in name only.
The mail box
/mail/box/a\f5
does not contain any messages from
/mail/box/a/b,
according to
upasfs(4).
