Hi Dean,
Sorry for not getting back to you sooner, but I am traveling and now in Europe. Plus I didn't get the email notice that someoone (you) had replied, even though I checked it.
Anyway, still doesn't work for me and yes, I've used multiple email addresses and still get the same error.
Do you think it's the html/text & sub/unsub feature? It's on one list, but not the others? I'll try it.
Thanks,
Greg
