|
|
|

|
|
A guide to postfix mail queue manageent can be found at

|
|
||
|
|
=item maildrop
|
||
|
|
|
||
|
|
Messages that have been submitted via the Postfix sendmail(1) command,
|
||
|
|
but not yet brought into the main Postfix queue by the pickup(8)
|
||
|
|
service.
|
||
|
|
|
||
|
|
=item hold
|
||
|
|
|
||
|
|
Messages placed in the "hold" queue stay there until the administrator
|
||
|
|
intervenes
|
||
|
|
|
||
|
|
=item incoming
|
||
|
|
|
||
|
|
Inbound mail from the network, or mail picked up by the local
|
||
|
|
pickup(8) daemon from the maildrop directory.
|
||
|
|
|
||
|
|
=item active
|
||
|
|
|
||
|
|
Messages that the queue manager has opened for delivery. Only a limited number
|
||
|
|
of messages is allowed to enter the active queue (leaky bucket strategy, for a
|
||
|
|
fixed delivery rate).
|
||
|
|
|
||
|
|
=item deferred
|
||
|
|
|
||
|
|
Mail that could not be delivered upon the first attempt. The queue manager
|
||
|
|
implements exponential backoff by doubling the time between delivery attempts.
|
||
|
|
|
||
|
|
=item corrupt
|
||
|
|
|
||
|
|
Unreadable or damaged queue files are moved here for inspection.

=head1 CONFIGURATION
|
||
|
|
|
||
|
|
By default "postconf -h queue_directory" is used to determine the
|
||
|
|
spool directory. Is postconf is not available in the $PATH then
|
||
|
|
/var/spool/postfix is assumed. This can be overridden by the
|
||
|
|
"spooldir" environment variable like so:
|
||
|
|
|
||
|
|
[postfix_mailqueue]
|
||
|
|
env.spooldir /var/spool/postfix
