Yes I already have a job to manually run the WP-CRON.php job from my own server. Therefore there shouldn't be any blockimg, locking or banning going on as I can send however many emails as I want.
All I need to know is where the code is that runs the auto-responder emails so I can put some debug code in to find out what is going on as I have checked the database tables and the newsletter IDs link up to the AutoResponder IDs so I cannot see a DB issue going on therefore it must be something in the code.
On my own plugins I have had issues with WordPresses inbuilt cron job and created my own (strictly-sitemap) to get round this issue which was related to class based objects being scheduled with the inbuilt cron job.
I would like to find the page/url that fires the AutoResponder job so I can set a cron job to fire it and debug what is going on to a log file. I can see when I run the "Run Now" button in admin it calls this page
This is a wordpress file so I am guessing the version code is somehow related to the plugin to fire something by AJAX.
However If I cannot get a fix from the author can I at least get a page name where the code is located or a logical spec e.g
-wp-cron job added to run it
-every Xmins this URL is called by the cron job
-this function X checks for any emails and puts them in the queue table
-the queue table is then emptied
Something like that would at least be handy to those of us who can debug code.
