Hello all, When I try to send a test email when the campaign has a specific delivery server selected (in the campaign's setup page > campaign delivery servers), I get the error "Email delivery is temporary disabled." This applies to either of the two delivery server options that I have configured. However, I can still send the campaign successfully. If I deselect all delivery servers, I can send the test email successfully. Mailwizz 1.7.2. How can I fix this?
