Re: SprintPCS spam policies

2004-06-24 Thread Eric Kuhnke

I just wanted to give everyone a heads-up on the antispam policies of
SprintPCS, so that you will know what to expect if you start getting blocked
by their mx.messaging.sprintpcs.com mail servers.
As a non-sprint-related side note, I know of somebody whose ATT 
Wireless phone service was rendered completely unusable by incoming spam 
via the email-to-SMS gateway.  The typical rate was one message every 30 
minutes, the only solution offered by customer service was to change the 
phone number.   Has anyone ever encountered spammers doing a dictionary 
attack (emailing all  phone numbers in a NXX) via email-to-SMS 
gateways?

If they didn't before, they surely will now.

I used to run an email to sms gateway at a previous job (where we 
consulted for one of india's largest mobile phone providers)

I was seeing multiple instances of this even 4..5 years ago.
