I upgraded to the newest version about 2 months ago and everything has been running real smooth. Then today, in the middle of mailing 98,000 people, I got this errror:
Sending error. Check your mail settings.

It look to me like I have a dead email address some where in there. With a ")", but I searched for ")" in the list and I can't find it. Any idea what to do? I can't mail to my list?
