Afternoon,
Just upgraded from version 3 to 4.2.0-beta2 and before tackling the upgrading the backend to MySQL and adding the bounce handler, I thought I'd better just test that everything was working A OK. I can log on as Admin fine but I've sent a couple of test mailings and also tried to subscribe from the form on the index page of the website but neither the test emails have come through to the list email address nor the confirmation email to the email address I used as a test for a new subscriber.
What can I next check to troubleshoot this problem?
Thanks.
