[tlug] Mobile carrier Mail delivery question

[Robert Fisher <robert@example.com>]

Good afternoon

This is my first time to post so I will introduce myself.  I am Robert 
Fisher, I am working for Inphase Co., LTD. which is a partner with 
DoubleClick Japan.  I am THE systems administrator at the moment.  I 
love Linux.  

I have a question for the group.  I want to send emails to mobile 
phones.  However, I have heard that the mobile carriers 
(docomo,vodafone,au) will start to block after so many emails coming 
from a MTA.  Has anyone heard something like this?  if you have, do you 
know where the hard proof is? 

Thanks in advance
