I am having a problem with Windows Mail (Comcast). Emails with several photos attached bounce back to the sender. I am able to receive email with 5 photos attached from an AOL account, but when someone with a Yahoo acccount tries to send the same, it bounces back to them, and I have no idea the attempt was even made, unless they email me without the photos and tell me. (A while ago, I had the same problem with another AOL sender as well.) Is there a setting I can change?
