All they give me is an email address that was supposed to clear things up within 12 hours - I am now 30 hours plus into the problem and getting nowhere - I am hoping someone has some new suggestions - they seem to be blocking IP addresses because of a MyDoom virus alert - and emails flooding their servers as a result - but I have checked every machine and we don't have this virus - so I am at a loss as to how to go forward from here.
