I am having the same trouble yesterday and today. Think I may have found something: I am using gmail accounts with comcast ISP. If I try to send to a "group" email, i.e. 18 people, I get the error from both my gmail accounts. But when I reduce the # of people it seems to send okay. Think maybe Comcast is flagging as possible spam and not allowing it. They are closed so I can't call them to check. Will do tomorrow - hopefully this is the issue. I have seen several others with this same post today.

Thanks for the reply...I've actually figured it out....I needed to set up my port to either 465 or 587. I chose 587 and seems to be working.....
