Blue dot next to message in sent box
I see that this question has been asked before but it has not been really explained.
When i check my "sent" box in Yahoo mail, certain sent messages have a solid blue dot
(indicating according to some people that the message has not been read) However, when I check with the recipient, they have indeed read the message! Sometimes i know this because they respond immediately and yet i still have a blue dot next to certain messages. I have not received a logical explanation as to why this is happening.
