I'm running v1.5.16 of Postie and it's setup and working perfectly when I click the run script button in the settings but I cannot get it to retrieve the posts automatically.
I've checked the event schedule with WP Crontrol and it runs with no errors
I've setup a schedule with SetCronJob. That also runs with no errors
I've also setup a cron schedule on the linux server (heart internet). This too runs with no errors yet the emails don't load in the blog.
