Newsletters seem to be working on and off, mostly off. I have registered one recipient (myself), I enter Subject and data, and hit Send Newsletter. I see a preview of the Newsletter, and:

The content of the Newsletter is recorded allright, if I press 'use', I get to send the same content again. I can see a whole range of newsletters, a few have been sent to 1 users, most to 0 users. Identical results on a different installation (2 users, any number of recipients in the range 0-2).
I have allowed users to subscribe to the newsletter I will ultimately use, we are migrating from a different system. Subscribe/unsubscribe seems to work, 14 registered so far, 5 confirmed. I expect hundreds of users will register in the coming weeks, but this worries me. Is it something about my setup, php-initialization, my ISP, anything *I* can do myself?
