Support Email problem

Having quite the big problem here, i have been trying to send an email to customer support on problems i am having. I can fill in all of my pc specs as well as the dxdiag and msinfo and both are under 5mb as stated i type in my problem and submit the mail, immediately afterwards i receive an email from the postmaster saying my mail in undeliverable and has not been sent due to exceeding size limits. The only
thing above 5mb is the description part itself but whether i type in one letter or 1000 it remains the same size at 6.5 mb.


The problems im requesting about should anyone have a solution is
1) whenever i click to enter a random dungeon the loading bar never loads and i remain on this page, the only way to get off is to close and restart WoW and by the time i do this i have either been kicked from the group or received the 30 min deserter

2) i would post this in beta forums but cannot do so since i have not fully opted in
I have installed the beta but when i launch it my screen goes black and the beta does not respond and closes

Thanks and excuse any spelling errors please
