Hello,
It is hard to understand the messages in ALL CAPS but I believe your problem is that you are using ALL CAPS when sending e-mail to other people. If you use ALL CAPS there are many spam filters that will block your messages as spam. Also, it sounds like you are wondering which e-mails you have sent in the past may have been blocked as spam. Unfortunately there is no way to know for sure unless the recipient tells you or your receive a bounce message with an error.
Is this the question and answer that you are looking for?
I hope I have answered the questions for you.
