I've been advised that since the server move, the notify emails are not always making it to their intended destination.
I've made some adjustments to the mail server that's running at deardiary.net, and the associated mailserver which actually does all the delivery work, and hopefully that'll fix it up. Some addresses though will almost never receive notifications - examples of this are hotmail.com addresses because Hotmail sees the notifications as spam and blocks us.
Give me a yell if you're still not seeing notifications after this, or indeed, if you are it might be helpful too so I can spot a pattern if things still aren't right.
Ta,
Steve
