Hi again. Fresh installation and I have been using fabulous and amazing phplist for many years, so think I know what I’m doing 
Case: this is an autoresponder and 1000 subscribers ‘ready’ to send.
Very bizarre: processqueue is running every 5 minutes, but it only sends 1 email at a time.
Issue: Config.php has standard settings, but I have been playing with domain auto throttle, wondering if something has become corrupt in database?

// 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 system:remote_processing [phpList Resources]
// 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.define(‘USE_DOMAIN_THROTTLE’, 0);
define(‘DOMAIN_BATCH_SIZE’, 1);
define(‘DOMAIN_BATCH_PERIOD’, 120);// if you have very large numbers of users on the same domains, this may result in the need
// 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.
define(‘MAX_PROCESSQUEUE_TIME’, 0);/*
Should I look in mysql, maybe something has not reverted to standard?
Any suggestions most appreciated, thank you.
