phpList is sending too fast

My hosting provider limits the number of emails sent to 200/hr.
I’m sending a small campaign (205 recipients) from the browser window.

This is the log message:

The following events occured while processing the message queue:

[Thu 7 Jun 2018 10:16] [myipaddress] Started
[Thu 7 Jun 2018 10:16] [myipaddress] Sending in batches of 100 emails
[Thu 7 Jun 2018 10:16] [myipaddress] Processing has started,
[Thu 7 Jun 2018 10:16] [myipaddress] One campaign to process.
[Thu 7 Jun 2018 10:16] [myipaddress] Please leave this window open.
phpList will process your queue until all messages have been sent. This may
take a while
[Thu 7 Jun 2018 10:16] [myipaddress] Report of processing will be sent
by email
[Thu 7 Jun 2018 10:16] [myipaddress] Processing campaign 9
[Thu 7 Jun 2018 10:16] [myipaddress] Looking for subscribers
[Thu 7 Jun 2018 10:16] [myipaddress] Found them: 205 to process
[Thu 7 Jun 2018 10:21] [myipaddress] Script stage: 5
[Thu 7 Jun 2018 10:21] [myipaddress] 65 messages sent in 300.70 seconds
(778 msgs/hr)

These are my settings in config.php:

define(‘MAILQUEUE_BATCH_SIZE’, 100);
define(‘MAILQUEUE_THROTTLE’, 2.0);
define(‘DOMAIN_BATCH_SIZE’, 1);
define(‘DOMAIN_BATCH_PERIOD’, 120);

Any ideas what to change?
Does phpList automatically continue sending? Now the windows is showing:

Sending in batches of 100 emails
Script stage: 5
65 messages sent in 300.70 seconds (778 msgs/hr)
80 failed (will retry later)
Finished this run
Less than batch size were sent, so reloading imminently

@veltsu Please review other questions on the same topic to find solutions others have used. Send speed is a common theme on this forum.

Yes, I’ve tried to find available solutions.

I don’t get this:

205 recipients
Sending in batches of 100 emails
65 messages sent in 300.70 seconds (778 msgs/hr)
80 failed (will retry later)
Less than batch size were sent, so reloading imminently

Would you please explain.

@veltsu Which part in particular? It’s not clear why the 80 failed. It’s likely that the 60 subscribers unaccounted for have already received the message before or are blacklisted.

This one particular. I have not yet succeeded to limit the output rate to less than 200 msgs/hr.

What about the automatic continuation?

@veltsu 778 is the calculated messages per hour based on the time sample available. E.g. if the installation continued sending at the same speed it sent during the last 5 minutes then 778 would have been sent. It is not the total actually sent.

The sending process will not continue because there is nothing more to send; all valid recipients detected were sent to.

I made these changes:
define(‘VERBOSE’, 1);

Let’s see how the next campaign sending behaves.

The sending of a new campaign did not work as expected. The send process stopped after 59 recipients. There were no errors. When nothing happend in about half an hour, I stopped sendind and restarted. Now phpList processed 49 recipients.
The the status windows started looping. I attach the related log events. The emails are (5.3 KB)
When I noticed the loop, I closed the window.
