Ok, thanks... I did finally find the log entries:

It is not really obvious to me what has caused this. Can you either fetch the email headers for me to look at or would you be willing to follow some directions to try a fake send to generate some diagnostic information?

You want me to do some diagnostic. Which mean, those email are active?

Here is 3 files:

a. Original send email.txt
b. guests-8519@toastmastersclubs_org.txt is the source of the return from server@toastmastersclubs.org
c. members-8519@toastmastersclubs_org.txt is working this summer

Ok, thanks! I now know what the problem is... If you look at the addresses you used below, you used BCC for the lists... we do not support BCC for any emails handled by the list server, because BCC is frequently used by spammers (it is for your protection against spam)... Basically, when you discount all the BCC'd addresses below that the list server will reject/not process because of BCC, all it had left was your email address which it cannot process because it is not a FTH list or anything it can expand. That is why you got the message you got... Move the BCC addresses to CC, and you should be fine. BCC is not needed, anyway, since we send emails to list members individually, so no-one in the list sees who else got the email.

You should have also gotten a bounce message because of the BCC... did you not get that?
