=head1 ABOUT
|
|
|
|
A guide to postfix mail queue manageent can be found at
|
|
L<http://www.postfix.org/QSHAPE_README.html#queues>
|
|
|
|
A summary:
|
|
|
|
=over 4
|
|
|
|
=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.
|
|
|
|
=item outgoing
|
|
|
|
Mails that are sent to the network.
|
|
|
|
=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
|
|
|
|
=head1 AUTHOR
|
|
|
|
Unknown.
|
|
|
|
=head1 LICENSE
|
|
|
|
Unknown.

|
=head1 MAGIC MARKERS
|

|
|

|
