I've run into a problem where hotmail seems to be the only email that I can not send any email too using sendmail (or postfix on a mirror test machine). (Fedora 7 system).
Has anyone else had the same problem and managed to find a fix for this issue. I've scoured the internet using Google and many people who run their own email server complain about this but I've found no pointers as to what to try next.
If anyone has any ideas it would certainly help me out a lot.
