Well, the first casualty of the new web server has been discovered: Hotmail.
Apparently the idiotic folks at Microsoft have determined that the server's new IP is in a huge range that was at some point used for spamming, and hence forevermore this range shall be blocked.
Please heed this advice: Do not sign up to yunix with a hotmail account. It will be deleted because the server cannot send mail to hotmail accounts.
I might do something about it later, but right now I'm happy enough to tell Hotmail to go shaft themselves for their pig headed draconian administration.
