QueueFileMode
Default permissions for queue files V8.12 and later
The files that populate a queue directory are the
qf, df, and xf files. The qf file (The qf File Internals on page 445)
contains envelope information and the message’s
headers. The df
file (The Data (Message Body) File: df
on page 398) contains the body of the message. The
xf file (The Transcript File: xf on page
401), when present, contains a copy of failed SMTP
replies and other error messages generated during a
delivery attempt.
If the SuperSafe
option (SuperSafe on page 1096) is
set to true, all messages are placed in the queue
prior to delivery. If that option is false (or
interactive beginning with V8.12), only messages
that fail to be delivered on the first attempt are
placed into the queue. When a message is placed into
the queue, the qf
and df files are
created. The permissions that the files get are
determined by this QueueFileMode option.
The QueueFileMode
option is declared like this:
O QueueFileMode=perms ← configuration file (V8.12 and later) -OQueueFileMode=perms ← command line (V8.12 and later) define(`confQUEUE_FILE_MODE',`perms') ← mc configuration (V8.12 and later)
Here, perms is the
permissions that will be given to the created files.
Those permissions are of type
octal. The default is 0600
(if the real-user-id is the
same as the effective-user-id),
and 0644 otherwise. If the mode has the
group-writable bit set (as in 0664), the
umask(2) is set to 0002 (disallow world-writable permissions) just prior ...
