That's what I originally thought as well, but it does not make sense. I have several lists. My first list has over 130,000 members on it. Emails go out fine on that list always.
The second list (that I have problems with) will not deliver ANY messages other than the auto-response (welcome email). After that, all emails I try to send, including the followups give an error like:
Sending error. Check your mail settings.

Server said:550 Administrative prohibition
I don't think it's my server because the server sends unlimited mails, and from a much larger list than this, even before AND after the errors with this list.
Thanks,
Cody
