So what are the causes of this? iResearch had some theories:
- User error: People enter email addresses wrong in the “send” form, causing emails that go nowhere or bounce back to the sender. Or, alternatively, users send emails that are too long or contain attachments too big for the receiver’s email servers, which rejects them.
- Server error: Servers break and emails get lost; also, some of the free services in China may not support some of the features included in more feature-rich emails, causing them to be rejected.
- Hackers: When all else fails to explain it, it was teh h4x0rz!
Personally I wonder if there aren’t more, ahem, official reasons for the lost mail ratio to be so high, but that’s just me.
