Queue and Load management

=========================================================================

// If you set up your system to send the message automatically (from commandline),
// you can set this value to 0, so "Process Queue" will disappear from the site
// this will also stop users from loading the page on the web frontend, so you will
// have to make sure that you run the queue from the commandline
// check README.commandline how to do this
define('MANUALLY_PROCESS_QUEUE', 1);

// This setting will activate an initial setup choice for processing the queue
// When "true" it will allow a choice between remote queue processing with the
// phpList.com service or processing it locally in the browser.
// when the value is "false", you can use remote processing in your own way
// as explain at https://resources.phplist.com/system/remote_processing
// define('SHOW_PQCHOICE',false);

// batch processing
// if you are on a shared host, it will probably be appreciated if you don't send
// out loads of emails in one go. To do this, you can configure batch processing.
// Please note, the following two values can be overridden by your ISP by using
// a server wide configuration. So if you notice these values to be different
// in reality, that may be the case

// max messages to process
// if there are multiple messages in the queue, set a maximum to work on
define('MAX_PROCESS_MESSAGE', 999);

// process parallel
// if there are multiple messages in the queue, divide the max batch across them
// instead of sending them one by one.
// this only works if you use batch processing. It will divide the batch between the
// campaigns that need sending.
//define('PROCESSCAMPAIGNS_PARALLEL',true);

// define the amount of emails you want to send per period. If 0, batch processing
// is disabled and messages are sent out as fast as possible
define('MAILQUEUE_BATCH_SIZE', 0);

// define the length of one batch processing period, in seconds (3600 is an hour)
define('MAILQUEUE_BATCH_PERIOD', 3600);

// to avoid overloading the server that sends your email, you can add a little delay
// between messages that will spread the load of sending
// you will need to find a good value for your own server
// value is in seconds, and you can use fractions, eg "0.5" is half a second
// (or you can play with the autothrottle below)
define('MAILQUEUE_THROTTLE', 0);

// Mailqueue autothrottle. This will try to automatically change the delay
// between messages to make sure that the MAILQUEUE_BATCH_SIZE (above) is spread evently over
// MAILQUEUE_BATCH_PERIOD, instead of firing the Batch in the first few minutes of the period
// and then waiting for the next period. This only works with mailqueue_throttle off
// and MAILQUEUE_BATCH_PERIOD being a positive value
// it still needs tweaking, so send your feedback to mantis.phplist.com if you find
// any issues with it
define('MAILQUEUE_AUTOTHROTTLE', 0);

// Domain Throttling
// You can activate domain throttling, by setting USE_DOMAIN_THROTTLE to 1
// define the maximum amount of emails you want to allow sending to any domain and the number
// of seconds for that amount. This will make sure you don't send too many emails to one domain
// which may cause blacklisting. Particularly the big ones are tricky about this.
// it may cause a dramatic increase in the amount of time to send a message, depending on how
// many users you have that have the same domain (eg hotmail.com)
// if too many failures for throttling occur, the send process will automatically add an extra
// delay to try to improve that. The example sends 1 message every 2 minutes.

// to run processqueue many times, when you use domain throttling. You can also tell phplist
// to simply delay a bit between messages to increase the number of messages sent per queue run
// if you want to use that set this to 1, otherwise simply run the queue many times. A cron
// process every 10 or 15 minutes is recommended.
define('DOMAIN_AUTO_THROTTLE', 0);

// MAX_PROCESSQUEUE_TIME
// to limit the time, regardless of batch processing or other throttling of a single run of "processqueue"
// you can set the MAX_PROCESSQUEUE_TIME in seconds
// if a single queue run exceeds this amount, it will stop, just to pick up from where it left off next time
// this allows multiple installations each to run the queue, but slow installations (eg with large emails)
// set to 0 to disable this feature.

// recommended to leave it off, but if you're very curious, you can enable it

// email address validation level [Bas]
// 0 = No email address validation. So PHPList can be used as a non-email-sending registration system.
// 1 = 10.4 style email validation.
// 2 = RFC821 email validation without escaping and quoting of local part.
// 3 = RFC821 email validation.
// This is an expirimental email address validation based on the original RFC. It will validate all kind
// of 'weird' emails like !#$%&'*+-/=.?^_`{|}~@example.com and escaped\ spaces\ are\ allowed@[1.0.0.127]
// not implemented are:
//   Length of domainPart is not checked
//   Not accepted are CR and LF even if escaped by \
//   Not accepted is Folding
//   Not accepted is literal domain-part (eg. [1.0.0.127])

// Time Zone
// By default phpList will operate in the Timezone of your server. If you want to work
// in a different Timezone, you can set that here. It will need to be a valid setting for
// both PHP and Mysql. The value should be a city in the world
// to find PHP timezones, check out http://php.net/manual/en/timezones.php
// You will also need to tell Mysql about your timezones, which means you have to load the timezone
// data in the Mysql Database, which you can find out about here:
// http://dev.mysql.com/doc/refman/5.0/en/mysql-tzinfo-to-sql.html
// make sure that the value you use works for both PHP and Mysql. If you find strange discrepancies
// in the dates and times used in phpList, you probably used the wrong value.

// In some systems (eg behind load balancing proxies) you may need to set the HOST to be something else
// then the system identifies. If you do, you can set it here.

// except when they are on another list.

//# message queue prepare
// this option will handle the sending of the queue a little bit differently
// it assumes running the queue many times in small batches
// the first run will find all subscribers that need to receive a campaign and mark them all
// as "todo" in the database. Subsequent calls will then work through the "todo" list and
// send them. This can be useful if the SQL query to find subscribers for a campaign is slow
// which is the case when your database is filling up.

// to validate the login for an administrator, you can define your own authentication module
// this is not finished yet, so don't use it unless you're happy to play around with it
// if you have modules to contribute, open a tracker issue at http://mantis.phplist.com
// the default module is phplist_auth.inc, which you can find in the "auth" subdirectory of the
// admin directory. It will tell you the functions that need to be defined for phplist to
// retrieve it's information.
// phplist will look for a file in that directory, or you can enter the full path to the file

// eg
//$admin_auth_module = 'phplist_auth.inc';

// or
//$admin_auth_module = '/usr/local/etc/auth.inc';

// Public protocol
// phpList will automatically use the protocol you run the admin interface on for clicktrack links and
// tracking images
// but if you want to force this to be http, when you eg run the admin on https, uncomment the below line

// with advanced bounce handling you are able to define regular expressions that match bounces and the
// action that needs to be taken when an expression matches. This will improve getting rid of bad emails in

// this is useful for old systems that have been created
// for valid engines, check your server documentation (MariaDB or Mysql)
// Warning, setting this value incorrectly will cause your database creation to break
