The only way for me to fix it is for me to go through the mail rejection logs and contact the administrators of the myriad of different anti-spam services and get them to remove us from their blacklists.
This will take some significant time investment so please patient.
If you're on Hotmail or MSN you will need to find a different e-mail address - deardiary.net will not send to Hotmail or MSN addresses due to the incredible amount of ignoramuses who sign up on notify lists and then a year later decide they don't want to be notified any more and instead of unsubscribing they just mark our e-mails as spam and get our servers blocked from sending legitimate mail to MSN/Hotmail.
Spam is a scourge... Anti-spam blocking lists seem to be becoming an even bigger scourge of late!
Anyway, I shall be working to clear the blacklists, but in the meantime if you're not receiving notifies to your e-mail address, please try using a different e-mail address at a different provider.
Thanks.
