When a J.D., a curezone user stops receiving email notifications, it is not because I don't want to send those notifications to him, and it is not because those notifications end up in his local spam or junk box.
The reason why he is not receiving email notifications is because his Internet services provider have just blacklisted CureZone mail server.
What does it mean?
If a mail server's IP address reaches a blacklist of an Internet service provider, that mail server can't send anymore email to any email address controlled by that Internet service provider.
CureZone mail server tries to send email to all those email addresses, but all emails are rejected.
But, just recently, hotmail.com, yahoo.com, gmail.com, rr.com, rocketmail.com and rogers.com joined the club.
And, many other smaller providers ...
Many people stopped receiving notifications.
CureZone mail server can't send a single email to any email address controlled by those services.
The question is not what I want, the question is what is possible.
Why do major Internet service providers choose to blacklist CureZone mail server?
One of the way to fight spam is to blacklist sources of spam.
If there is computer out there, sending 50,000 spam emails per day, it is better to blacklist it, then to use a lot of computing power to "read" each single email and determine if it is spam.
Every time a new message is posted on CureZone Forums , Curezone mail server would send from 10 to 200 email notifications to all CureZone users who, by their own will, subscribed to receive email notifications.
On average, a single forum message would trigger sending 30-40 email notifications.
During a single day, there could be 2000 new forum messages posted on CureZone.
That results in 80,000 email notifications sent in one single day.
One single computer keeps sending 80,000 emails per day.
If you are a technician, working for AOL, and you see that there is a single computer out there, sending 80,000 emails per day, and all of those emails look extremely similar, you could easily decide that this could be spam, and you just blacklist the CureZone mail server with a single click of a mouse.
There is no way for me to fight against those technicians. They just happen to have too much power, and the procedure of getting whitlisted is far more complicated then it takes to get blacklisted again.
It is enough that 1 person a day contacts them and complains that CureZone sent spam to them, and they would trust more to their customers then to me.
You can bet that CureZone have more then one single enemy per day.
So, sure, inbox is not the best solution, ... it is the ONLY solution.
