My out going private messages are not being recieved.

For some reason the people I am sending private messages to are not recieving them. My controll panel shows the messages to be sent.

Recently I sent a pm to Rockelle, my control panel showed it to be sent and never read by her. I asked her to check her pm's in a thread and she sent me a pm stating she never got a pm from me. I responded to her pm and i'm pretty sure she never got my response.

Thanks.
Please disregard this post. Seems like everything is working ok. Sorry for the inconvinience.
