First of all this is a little hard to understand you are not totally clear.

If you are just trying to send a message and mebers are not recieving it could be a host thing. You're server/host could be blacklisted, and not dolphin related. Going to your home page? what exactally are you saying? You are logged in as a member trying to message another member? What dolphin version?

Things that could be more helpful would be what version of dolphin, what exactally are you doing or trying to do. see more Clearer the better. There are so many dolphin versions now and patches. So many things that could be clearly described would help alot.
